Abstract

The present invention relates to a virtual domain system, which can expand the Internet system by means of a conversion program input to a server's computer. More particularly, the present invention relates to a virtual domain system, wherein if a virtual domain name is input to a virtual domain conversion program by an applicant it is linked to a web site by a domain name of the ICANN system. According to the present invention a virtual domain conversion program is installed in a server's and a client's computer and enables the use of a virtual domain, instead of one of the Internet system used in ICANN, by means of converting, on a server's or a client's computer, the virtual domain input by a client into an ICANN system.

ft VIRTUAL DOMAIN SYSTEM

Technical Field

The present invention relates to a domain system, which provides more accurate and representative domain names with a variety of options. It is a system, which provides links by way of inputting a virtual domain by a client, and then comparing said virtual domain database with the conventional domain database.

Background of the Invention Use of computers is in a trend of fast increase. In particular, use of the Internet is in fact rapidly getting popularized. Fig. 1 below is a block diagram to show, roughly, a general aspect of the Internet service. In order to have access to the Internet the user of a computer raises the web browser 14 on his computer 10. The web browser is possessed of a program for communication with both a client's computer and that of an Internet server. In most Internet communication, the user of a computer sends his request 16 off via his personal computer 10 to a server's computer 18. The request 16 indicates either location or web site of the server which he wants to get connected with.

In response to the request 16 the server 18 sends off the required web page 20 information. In most cases the web page 20 information has HTML (Hyper Text Markup Language) and different hyper link information of other web sites. The web

* browser 14 has got hold of a software program for indication of said web page 20 on the user's computer 10 for him to see the web page 20 he desires.

Then the address of the server to which the client wants to proceed enters on the address window (also called URL: Uniform Resource Locator) his domain address, as is shown in Fig. 2. A browser on an Internet Explorer program is possessed of a box 24 for entry of his address in the given area of the user's space 26 on a window 22.

The Internet's web sites are most concerned with their use in publicity of domains, making them available to use by enterprises upon selection for their rational and creative values relative to consumers or customers. In accordance with the trends of Internet markets, therefore, enterprises are alert to the vogues of domain names, evaluate their actual assets, and adopt ones for use as brand names symbolizing their businesses.

Despite such great importance of domain names what is ordinarily available as top level domains among the domain names in the system of ICANN (Internet Corporation for Assigned Names and Numbers), which has so far performed assignation and administration of the spaces for addresses on the Internet, is confined, roughly, to such abbreviations as org, net, com, gov, mil, int, etc., and such two English alphabetical letters representing for particular people their nationalities as kr, jp, etc.

In a domain system in the fashion of ICANN such as are said above, it is not merely difficult to carry the characteristics of Internet web sites when the third-level domain names which one can choose at liberty are the same, but can hardly secure exactitude or precision for so many are extracted in a search.

In the ICANN system, moreover, the available number of domain names cannot but be limited, wherefore, supply of domain names is anything but smooth and arouses, indeed very often, disputes among nations and enterprises over domain names.

Summary of the Invention

An objective of the present invention is to provide Internet users with a virtual domain system more efficient than before by supplying a system which uses virtual domain names more precise and symbolic than otherwise.

Another objective is to provide a new program for search of domain names which enables a precise and efficient checkup on Internet web sites or other similar material.

The virtual domain system of the present invention intended to achieve such objectives consists in the use of virtual domains, instead of the Internet domain system used in ICANN, by converting the virtual domains via a conversion program memorized in a client's or a server's computer; wherein, input virtual domains are converted into domains of the ICANN system on a client's or a server's computer and linked thereto, thereby materializing the basic technical ideas of the present invention.

The virtual domain system of the present invention is characterized in that it consists of a step of accepting a request in English of a computer user for a virtual domain name and a step of converting the thus input virtual domain name into one of the ICANN system for a checkup on a one-to-one basis.

It is also characterized in that the system of the present invention consists of a step of receiving an request in English from a client desirous of a possible registration of his virtual domain name, converting the requested-for domain name into one of the ICANN system and checking it up one to one; a step of searching the databases which store information on domains to obtain information on the input domain at the request of the client's computer; a step of providing the results of the search to the client's URL search window; a step of receiving information from the client on the virtual domain he chooses and converting it into one of the ICANN system; and a step of proceeding to the home page of the converted ICANN system domain.

Detailed Description of the Preferred Embodiments Below, the Internet domain system by the present invention is described in detail, the attached drawings being made reference to. Fig. 1 is a flow chart to show the proceeding of the Internet domain system by the present invention.

A client desirous of a virtual domain name sends a server a letter of a request in the given form for registration of his chosen domain name. In this step, the client or a server furnishes his computer with a virtual domain conversion program and applies, via the program, for assignation of a virtual domain name characterizing his desired web site. For instance, the administration of the Republic of Korea may adopt "korea" and so may the administration of the United States of America "america," as a virtual domain name, of a single unit, neither a second nor a third unit being suffixed.

A word, its abbreviation, or a word in its plural form, representing a type of business can also be used. Instances are "bank" in the case of a financing agency, "news" for an information medium, "food" for a business related to edible stuff, "shop" for a store or shopping mall, "car" or "auto" when related to auto-vehicles, "air" when related to air-craft business, "train" for business related to railroads, "market" if related to a market place, "video" when in relation to that item of merchandise, "telecom" if relative to telecommunications, "electron" pertaining to electronics engineering, "led" related to liquid crystal, "thinfϊlm" in relation to thin membranes, "tft" relative to thin membrane liquid crystal, "soi" if related to an industry of vaporization of electric substances on silicon, "phone" in relation to telephone communication, "mobilephone" in the case of a wireless, "commerce" if related to a commercial business, "garden" or "park" in the case of a public resort, "flower" if related to flowers, "semicom" or "semiconductor" if related to a semiconductor business, " furniture" when related to household fixture, "fashion" if related to clothing, " electric" if related to electrical industries, "movie" or "film" if related to cinematographic industry, "temple" if related to a place of worship, "film" if related to manufacture of that stuff, " jewel" if related to jewelry, "mp3" if related to MP3, "firm" in relation to ordinary commercial business, "store" if related to ordinary vending business, "tour" or "travel" when related to journey, "book" in the case of a bookseller, "card" or "credit" if related to a business in credit cards, " stock" if related to shares, "finance" if related to banking, " insurance" if related to that branch of business, "perfume" if related to perfumery, "cosmetic" if related to toiletry, "tool" if related to implements or machine tools, "mechanic" or "machine" if related to machinery, "dining" or "restaurant" if related to an eating establishment, "church" if related to Christian organizations, "web" if related to the Internet, "art" if related to the arts, "sports" if related to athletic activities, "sex" if related if anything to genders, "rec" if related to recreations, "info" if related to information, "uni" or "college" if related to the institutes of higher learning, "school" if related to an organization of education, "chod" if related to a company dealing in chemicals, "inst" if related to an institute or association, "power" if related to a power company, "energy" in the case of a business related to energy, "environ" or "environment" if related to environmental affairs, "water" if related to things aqueous, "oil" if related to petroleum or other oils, " cyber" if related to imaginary world, "star" if related to the stars, "cosmos" or "universe" if related to the universe, "moon" if related to the moon, "pc" if related to personal computers, "computer" if related to computers, "tv" if related to televisions, "music" if related to music, "picture" or "fineart" if related to the fine arts, "sound" if related to sounds, "voice" if related to vocal sounds, "construction" or "architecture" if related to building, "clinic" or "hospital" if related to medical institutions, "pet" if related to pet animals, "fish" if related to fishes, " sea" or "marine" if related to seas, "cattle" if related to domestic animals, "hall" if related to a venue of public performances, "group" if related to conglomerates or business groups" etc., etc., while it is possible to use in this system, too, such words as "org," "net", "com," "edu," "gov," "mil," "int," and such two-letter words representing the names of countries as "kr," "jp," etc., etc., all commonly used in the ICANN system. Because, when a server links an input name to his conversion program with ICAAN-based names or when the alphabet letters of a name are converted into numerical figures in three digits and sent to a server, then the server will link them with ICANN-based Internet domain names so that the relevant web site can be made available to an Internet user. If in the aforesaid stage of a request the applicant has not registered an ICANN-based domain name, a domain name of a second or higher level in the ICANN system can arbitrarily be registered to get linked to the relevant web site.

Here the way of linking is, as has been described above, either by linking a domain name input through the virtual domain name conversion program with one of the ICANN system, arbitrarily registered by the server, or by converting each of the alphabet letters into a numerical figure in three digits and sending it to the server, and then linking it with the one ICANN-based domain name which the server arbitrarily has registered. This way, it is preferable at the stage of a request to adopt, in a domain name of the top level, one or more of the letters particularizing the web site or rather leave the space blank, while it is quite all right even if one and the same address is used for registration for both the virtual and ICANN-based domain names (S 1 step).

The virtual domain name included in the request transmitted by a client computer and the ICANN-based domain are mapped one to one and made into a database. Taking the example of an ICANN-based domain name http ://www.earthl 23.com and its IP address 295.17.357.85, it is possible, when a virtual domain name http://www.earth.star is applied for, to have it directly linked by the conversion program with an ICANN-based IP address 295.17.357.85, too. When, as in this case, it is to link one through an IP address, the alphabet letters can each be converted into figures for the linking. In other words, figures are assigned to the alphabet letters in order as 011 to "a", 012 to "b", 013 to "c", viz. the numbers from 011 to 036 to the 26 letters, one each. Here, the why that the numbers from 001 to 010 are not used is to avoid collision with use of actual figures, and the why that each three figures start with "0" is to distinguish alphabet letters from actual numbers or regular figures. Converting the letters used in http://www.earth.star by the use of the virtual domain name conversion program by changing "e" to 015, "a" to Oil, "r" to 028 and in this order and by means of transmitting the converted name to the server, it is made possible for the server to link the name with the ICANN-based domain registered at the time of the request so that access is made to the proper web site.

Below, the actual performance is described in detail. To create a virtual domain a name server becomes necessary. This name server assumes the role of matching such an IP address as 111. HI.111. HI with such a domain name address as www.daum.co.kr, one to one. Admittedly, if a name server is not employed it is yet possible to approach a desired server by using an IP address alone, but if a name server is employed it is better possible to reach the desired server through a domain name instead of an IP address which is anything but easy to learn by heart.

A name server is possessed of such files as follows:

/etc/resolv.conf

/etc/host.conf /etc/hosts

/etc/named.conf

/etc/named.boot

/var/named/domain.zone

/var/named domain.rev

Of the above the existing contents of the named.conf file are as follows:

//generated by named-bootconf.pl options directory "/var/named"; /*

*If there is a fire\wall between you and nameservers you want *to talk to, you might need to uncomment the query-source *directive below. Previous versions of BIND always asked *questions using port 53, but BIND 8.1 uses an unprivileged *port by default. */

//query-source address * port 53;

//

//a caching only nameserver config //

By editing the contents of such a named.conf file with the use of the vi editor, the editor used in Unix or Linux, a virtual domain is created.

Taking, for example, the case of an request-for domain name of

"samsung.car.shop," made of a small classification (samsung), a medium classification (car), and a large classification (shop), the way of its registration in the named onf file is described here. (In the description below, the window is OS, the browser as Explorer)

First, as shown in Fig. 4a, performance starts with pressing the button "START" in the bottom of the window, and next choose "RUN". Then, as shown in Fig. 4b, enter "telnet" on the address window, followed by the IP address of the name server, press the button for, and try access. Then, as shown in Fig. 4c, the instruction "login" will come up on the window. Enter the access ID, and press "ENTER". The "Pssswd" will come up, a demand for entry of the password. Write the password, press "ENTER", and the connection gets through, the prompt format: [root@wave21c.com]. If the instruction "[root@21c.com] vi named. Conf ' is given the contents of the above- said named, conf will come on the screen. Manipulating the direction key, move the cursor downward and add the parts of: Zone "car.shop" type master; file "temp/car. shop" and by this correct the named. conf to read: //generated by named-bootconf.pl options directory"var/named" ; /*

*If there is a firewall between you and nameservers you want *to talk to, you might need to uncomment the query-source *directive below. Previous versions of BIND always asked

*questions using port 53, but BIND 8.1 uses an unprivileged *port by default. */

//query-source address * port 53; ;

//

// a caching only nameserver config // zone "car.shop" type master; file "temp/car. shop"

The required contents of a virtual domain are entered in addition in the bottom of the named onf file this way, and here the entry of an address (xxx). car. shop means a demand for reference to the document entitled "car.shop" contained in a temp directory. Then it is necessary to prepare a file "car.shop" in the temp directory. This time a vi editor, the editor used in Unix or Linux, is used. When the name server is connected with, the words [root@wave21c.com] come up. After preparing a temp directory, a carshop file is made by the use of a vi editor.

To make the temp directory the following is written on the screen: 10

[root@wave21c.com]mkdir temp

Given this instruction, the temp directory is made, and then enter: [rood@wave2 lc.com] vi car.shop

Now, as the picture as shown in Fig. 4d appears on the screen, press "i" (instruction for inputting) and write the following:

@ IN SOA localhost.root.localhost. ( 1999052500; Serial

28800; Refresh 14400; Retry 3600000; Expire 86400); Minimum IN NS localhost.

Samsung IN A 243.432.53.1 prime IN A 123.432.12.43

By giving a virtual domain name of "samsung" and "prime" and entering an IP address to be connected with it, a list is thus made. As many as the number of the lists the number of the Serial (the second line: 1999052500; Serial) is also to be increased to.

Example)

(a SOA localhost.root.localhost. (

1999052500; Serial 28800; Refresh 14400; Retry 3600000; Expire 86400); Minimum

ΓN NS loclahost.

Samsung IN A 243.432.53.1 prime IN A 123.432.12.43

The virtual domain name is added to the car.shop file.

@ ΓN SOA localhost.root.localhost. (

1999052501; Serial 28800; Refresh 14400; Retry 3600000; Expire 86400); Minimum

@ IN NS loclahost.

Samsung IN A 243.432.53.1 prime IN A 123.432.12.43 sinjong ΓN A 123.483.384.7

Like this, the Serial has to be increased by one (1999052500 →l 99905250 l)Then after inputting all data to the file, press Esc, ":" (Shift + :), and the letter "w" (for save) and finally the letter "q" (quit). All is through now.

In case the requested-for virtual domain name is one such of a medium (daum) and a large (mail) classifications as "daum.mail" the same process is followed as in the case, where a virtual domain name is registered on a named, conf file and it is made of a small, a medium, and a large classification (say, samsung.car.shop).

After access to the server by telnet, the named, conf file is corrected by the use of a vi editor. What is to be corrected in this case follows: zone "mail" type master; file "temp/mail"

In other words, such a domain name as contains a word "mail" like "daum.mail", "kebi.mail", or "lycos.mail" is meant to make reference to the document on mail in the temp directory. 12

Next, a "mail" file is made in the temp directory. But since the temp directory has already been made above, now just transfer to the temp directory and make the mail file: [root@wave21c.com]c temp

Then [root@wave21c.com] changes to [root@wave21c.temp]: [root@wave21c.temp] vi mail

When a scene, as shown in Fig. 4e, appears, press the alphabet letter "i" (input), and write as follows:

@ IN SOA localhost.root.localhost. (

2000102403; Serial 28800; Refresh 14400; Retry 3600000; Expire

89400; Minimum

In NS localhost. daum IN A 211.111.78.0 kebi IN A 478.382.382.98 lycos IN A 123.433.384.12

After writing this, press the key "Esc" and next the key ":" (Shift + ;) placed in the middle right. Then write the alphabet letter "w" (save), and press the key "Enter". Write the alphabet letter "q" (quit), and press the key "Enter". As has been said above, be sure to increase the number of Serial to equal the number of the registered virtual domains.

Next, in case a virtual domain name in the style of large classification like "samsung" it is necessary to correct the contents of the named,conf file after connection with the name server through telnet, as has been described in 1) and 2) 13

above.

The part for correction at this time follows: Zone "samsung" typemaster; file "temp/samsung";

Next, to create a Samsung file in the temp directory transfer to the temp directory and create the necessary samsung file by the use of the vi editor: [root@wave21c.com]cd temp [root@wave21c.temp] vi Samsung

When such a scene as is shown in Fig. 4f comes up, press for the alphabet letter "i" (instruction to input) and write as follows:

@ IN SOA localhost.root.localhost. (

2000102403; Serial 28800; Refresh 14400; Retry 3600000; Expire 86400); Minimum

ΓN NS localhost.

Samsung. IN A 123,456.789.0 sori. ΓN A 987.374.234.2 pingpong. IN A A 343.467.32.24

After having written all these, press the key "Esc", and the key ":" (Shift + ;), write the alphabet letters "w" and "q", and finally press the key "Enter", thus completing the process.

Meanwhile, the way of providing some specific information on registration with a computer network is as follows. When desirous of connection with the Internet 14

through the Explorer, write down the domain name on the address window, and the resultant values required by the user are always obtained through search of the IP address via the name server. If there is no IP address of such a domain name the user wants with a name server it will yet be available from another name server (KR, COM, NET, etc.). A connection with a virtual domain name is only possible through access to a name server in possession of information on virtual domain names, to secure the desired values.

Place the cursor at the network icon and click twice on the right half of the mouse, and a pop menu, as shown in Fig. 4g will show. Choose "R" (Properties) in the undermost. Thereafter, when the dialog box shows, pick out the item "TCP/IP" and, next, choose "R" for registration information. Then another dialog box for TCP/IP, as in Fig. 4i, appears, and it is required to pick up the tab "DNS configuration", put the IP address of the name server in the space under "the address of the wanted DNS server", and choose the "OK" button.

In case a dialog box appears saying "for request of contents of new creation work the system over again", as shown in Fig. 4j, press the button "yes" and repeat the process once again (S2 step).

The client searches a web site by the use of a virtual domain. At this time it is possible to input a virtual domain name or an ICANN-based domain name address to his address window (URL). For such a stage of search as this the client or the server must be equipped with a virtual domain search program, which program may preferably be connected with a web browser or a portal site (S3 step).

The server analyzes a demand for search to confirm as to whether it is one for a virtual domain or an ICANN-based domain (S4 step).

In case it is a demand for search of a virtual domain, the relevant information on the domain is searched through a database table mapped one to one against ICANN 15

domains (S5 step).

The search completed, its results are transmitted to the client's computer. The virtual domain search program used for the present invention is preferably one, which shows in one frame both the URL window using the domain and the search window capable of searching of virtual domains; and the method for searching in the present invention shows the searched virtual domain in a text made into a database on the monitor, while, by contrast, conventional search engines showed only the domain and its contents. For instance, if a virtual domain searches a web site "universe", such virtual domain names containing the word "universe" and associated with the virtual domain system as, for example, universe.com; unverse.net; universe.start; universe.inst; universe.film; universe.group; universe.company; universe.res; etc. , as shown in Fig. 5, are displayed on the screen.

And if "star", a domain name of the top level, is searched, a scene comes up with such words containing information on a star as venus.star; moon.star; stum.star; sun.star; mercury.star; mars.star; etc., as shown in Fig. 6, on the browser, making it possible to search a site with "star" as its top-level domain name. Since the virtual domain search program used in the present invention can be made advantageous use of by linking with a web browser or a portal site, an Internet user can use it either via a web browser or by rapidly transferring to a desired web site upon searching of the domains through connection with a portal site (S6 step).

When a client sees the search data shown on a given space for a browser and clicks the cursor on a desired item he can bring up a selective signal for the relevant web site. The chosen signal is transferred to the server (S7 step).

In case the virtual domain system of the present invention is established with a client's computer, each alphabetical letter of the words registered as a domain name with his computer is converted into figures of three digits and transferred to the server, who links the virtual domain with the relevant ICANN-based domain names. It is 16

preferable that a virtual domain conversion program be used, thus, in link with a browser or a portal site, and it is also possible so to have the said virtual domain conversion program established with a client and a server that an input virtual domain can be converted only by the server equipped with the program into an ICANN-based domain name (S8 step).

The aforesaid converted virtual domain can be transferred to an ICANN-based domain and displayed on the web browser of the client's computer (S9 step).

If the above domain search information is for search of an ICANN-based domain, the relevant domain of the ICANN system is searched (S10 step), and transfers to the IP address resultant from the search to be displayed on the web browser of the client's computer. In case, as is shown in the explanatory example 1) above, if the words "samsung car. shop" or "prime.catr.shop" are entered, the relevant IP address is retrieved from the name server and outputted by the home page (SI 1 step).

The present invention has been described by the above examples alone, yet the present invention is not necessarily confined to these, and its variations and modifications can of course be worked out so far as such do not deviate from its proper category and technical thought.

Industrial Applicability
