It is default to first pass through Cloudflare interface lookup CDN source station address, if can not find, then by being searched in the Phpinfo page, if
Still it can not find, then searched by the e-mail server address of targeted website；It for another example presets to first pass through and be searched in the Phpinfo page
CDN source station address, then by Cloudflare interface lookup, still can not find if can not find, then pass through the postal of targeted website
Part server address is searched.
It is known that Cloudflare is the transnational science-and-technology enterprise in a U.S., provide including CDN, optimization work
The services such as tool, safety, analysis and application, are used to help protected website and resist including Denial of Service attack
(DenialofService) most of network attacks including, it is ensured that the website is online for a long time, while promoted website performance,
Access speed is to improve visitor's experience.And Cloudflare interface is a kind of query interface, can be used for inquire with
The real server address of the user of Cloudflare cooperation judges that targeted website has CDN virtual address so working as, that is, shows
It when the targeted website has virtual server address, at this moment can be inquired in Cloudflare interface, attempt to obtain mesh
Mark the real server address of website.In this step, especially by inputting above-mentioned targeted website on Cloudflare interface
The querying command of domain name is searched, when passing through the real server address of Cloudflare interface polls targeted websites,
Query result can be returned, if the targeted website is the user cooperated with Cloudflare, the true of the targeted website can returned
Real server address, if the targeted website is not the user cooperated with Cloudflare, return display inquiry less than as a result,
Lookup is not only convenient simple in this way, and obtained result is more accurate.
By in the lookup mode that the Phpinfo page searches above-mentioned CDN source station address, the above-mentioned Phpinfo page
Phpinfo function is mainly used for Web Hosting and tests whether the PHP environment built is correct, and many websites are being completed in the process
There is no deletions in time afterwards, therefore when accessing these test pages, the key message of meeting export server, such as export server
The multiple variables of running environment, the parameter of the inside include CDN source station address, so building when targeted website is tested in process of construction
PHP environment after, if without deleting these data in time, can by the Phpinfo page search targeted website key letter
Breath, to obtain above-mentioned true server address, i.e. CDN source station address.Specifically, input can be passed through
Phpinfo.php order is searched, as the domain name of access target website direct in the Phpinfo page adds phpinfo.php
Order when such as searching the CDN source station address of www.baidu.com, can input baidu.com+ in the Phpinfo page to search
Phpinfo.php order is to get to returning the result.When the key of the normal displaying target website of the phpinfo page found out
Information can obtain the CDN source station address of targeted website, the CDN obtained in this way by input order from these key messages

Card, so that it is determined that whether the CDN source station address is correct, wherein the domain name of safety group website is www.pingan.com, is searched
The CDN source station address arrived is 202.202.202.202, then www.pingan.com is directed toward by host first
202.202.202.202, access www.pingan.com then by browser is removed, if normally opening the website of safety group,
Prove that CDN source station address 202.202.202.202 is the true server address for www.pingan.com.
In one embodiment, with searching the CDN source station above by the e-mail server address of the targeted website
The step of location, comprising:
Step S4: the e-mail server address of the targeted website is obtained；
Step S5: identical associatedly according to e-mail server address acquisition and described e-mail server address C sections
Location；
Step S6: the association address is verified one by one to search the CDN source station address in the association address.
In the present embodiment, due to needing to obtain before obtaining above-mentioned association address according to the e-mail server address
The e-mail server address of above-mentioned targeted website, specifically, above-mentioned steps S4, comprising:
Step S40: the mail exchange record of the targeted website is obtained；
Step S42: the e-mail server address of the targeted website is obtained in the mail exchange record.
Above-mentioned mail exchange record is also referred to as mail route record or mx record, it can be directed toward a mail server,
Mail server is positioned according to the address suffix of receiver when sending out mail for e-mail system, i.e., recording on mx record has
E-mail server address.In step S40 and S42, the mx by inputting instruction unpack targeted website is recorded, and is then recorded in mx
In check the e-mail server address of targeted website.Specific method includes: that ding order is inputted in mx record, such as inputs ding
Mx and targeted website domain name are inquired, if what is obtained is alias, then the order of ding alias are inputted, to obtain mail
Server address.
Above-mentioned mail server is a kind of equipment for being responsible for E-mail receiver/send management, is corresponded to if targeted website has
Mailbox, if targeted website company have corporate mailbox, that is, show targeted website have above-mentioned mail server, work as target network
The company stood carries out receiving and dispatching mail using above-mentioned corporate mailbox, then targeted website mail service can be found in mx record
E-mail server address used in device, and because mx record is by " 25 mail transmission/reception port " and " 110 mail transmission/receptions
This port connection in port ", it cannot be accessed by CDN, so the e-mail server address on mx record will not be CDN void
Quasi- address, i.e. it is not virtual address that e-mail server address, which is true address,.Due to the mail server of corporate mailbox
Location and company's site's server address are generally C sections of identical two adjacent addresses, so e-mail server address is found out, that
Other adjacent server address identical with its C sections are possible to be exactly the targeted website CDN source station address.
In step s 5, identical associatedly according to the acquisition of above-mentioned e-mail server address and e-mail server address C sections
