Description
Technical Field
The application relates to a method, a system, an electronic device and a medium for acquiring an IP address of a source station.
Background
A Content Delivery Network (CDN) has a basic idea of avoiding bottlenecks and links on the internet that may affect data transmission speed and stability as much as possible, so that Content transmission is faster and more stable. By placing node servers at various positions of the network to form a layer of intelligent virtual network on the basis of the existing internet, the CDN system can redirect the request of a user to a service node closest to the user in real time according to network flow, connection of each node, load condition, distance to the user, response time and other comprehensive information. The core purpose is to enable the user to access the network nearby to obtain the required content, solve the network congestion condition and obviously improve the response speed of the user to access the website or the downloading speed of the user.
The CDN stores the content of the Web site on CDN nodes which are distributed all over the country or even all over the world, and the user can obtain the content cached on the CDN nearby by accessing the Web site, so that the access speed is improved. After the CDN is started, user access in different regions can be different servers, a real server (source server) of the Web site generally only needs CDN nodes to access and obtain, and CDN node servers accessed by users in all regions of the country do not directly access the source server, so that broadband resources of the Web site server can be introduced, and the server pressure is reduced.
Currently, a number of websites use a CDN technology, but after the CDN technology is used, external access can only pass through the CDN, and a source station cannot be directly found. In some scenarios of malicious web pages or trojan control servers, the source station needs to be found to analyze or track the problem. Therefore, how to acquire the source IP address of the website in the network security field has become a significant issue.

It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present application.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
One embodiment of the present application provides a method for acquiring an IP address of a source station, and referring to fig. 1, the method includes the contents of steps S101 to St 02:
step S101, an IP address set is obtained, whether the IP addresses in the IP address set are alive or not is judged, if yes, the alive IP addresses are stored as a first IP address set, and the IP addresses in the first IP address set are accessed through an HTTPS request.
Wherein, the acquiring the IP address set includes: and acquiring the IP address under the preset condition, wherein the preset condition comprises a preset area and a preset IP protocol version. The predetermined area may illustratively be worldwide, china wide, and so on. Common IP addresses in the preset IP protocol version are classified into two categories, i.e., IPv4 and IPv6, by the IP protocol version. The IPV4 has 4 segments of numbers, each segment not exceeding 255 at the maximum. IPv6 employs a 128-bit address length. In addition, the preset conditions can also comprise preset IP address categories and the like, the IP address addressing scheme divides the IP address space into A, B, C, D, E five classes, wherein A, B, C is a basic class, and D, E is used as multicast and reserved. The preset condition is not specifically limited in the embodiment of the present application, and may be one of the above multiple preset conditions, or a combination of multiple preset conditions, so that the actual limitation may be performed according to actual situations.
In addition, the determining whether the IP address in the IP address set is alive includes: and judging whether the IP addresses in the IP address set are alive or not through a detection tool nmap. The detection tool is used for filtering the IP addresses, and the IP addresses which do not survive are filtered, so that the complexity of subsequent judgment is reduced. The detection tool nmap is the Network Mapper. The method has three basic functions, namely detecting whether a group of hosts are online or not; secondly, scanning a host port and sniffing the provided network service; the operating system used by the host can also be inferred, the operating system can perform ping scanning when detecting whether the IP address is alive, the host responding to the scanning can be printed, and the like, and the detection tool nmap is used in the prior art and is not described in detail herein. In addition, the embodiment of the application also does not limit the tool for detecting whether the IP address is alive, and only needs to judge the survival of the IP address.
In a possible manner, before the determining whether the IP addresses in the IP address set are alive, referring to fig. 2, the step S101 further includes the following steps:
step S101a, obtain a CDN node IP address.
Wherein, the obtaining process is to obtain the IP address of the CDN node through the IPIP database or the GeoV2 database. Net, for example, by entering IP, obtains the IP address of the registered CDN node. The obtaining process is the prior art, and detailed description is not repeated herein in this application embodiment.
Step S101b, determining whether the IP address set includes the CDN node IP address, and if so, deleting an IP address in the IP address set that is the same as the CDN node IP address.
And by filtering the IP addresses containing the CDN nodes, the complexity of the subsequent steps is reduced. Thus, the elements in the first set of IP addresses obtained by step S101 are alive and do not contain known CDN node IP addresses.
Step S102, obtaining return information of the HTTPS request access, judging whether the return information contains a domain name, if so, establishing a relation between the domain name and an IP address in a first IP address set, and taking the IP address with the established relation as a source station IP address of the domain name.
In a feasible manner, the step of acquiring the return information of the HTTPS request access and determining whether the return information includes a domain name may be implemented by the following steps S201 to S203, referring to fig. 3:
step S201, acquiring an HTTPS certificate in the return information of the HTTPS request access.
When the HTTPS requests access to the connected IP address, an HTTPS certificate may be acquired from the access request return message. The HTTPS certificate is an HTTP SSL certificate, complies with an SSL protocol, is issued by a trusted digital certificate authority CA after the identity of the server is verified, and has the functions of server identity verification and data transmission encryption. Where the HTTP SSL certificate binds to the domain name and not the IP address.
Step S202, judging whether the domain name to which the HTTPS certificate belongs is returned in the HTTPS certificate.
Since the HTTP SSL certificate is bound to a domain name rather than an IP address, it is determined whether the domain name to which the HTTPs certificate belongs is returned in the HTTPs certificate, and if so, it is determined that the access to the IP address to which the HTTPs request to access the connection is successful, and the domain name to which the HTTPs certificate belongs is returned.
Step S203, if yes, acquiring a domain name to which the HTTPS certificate belongs.
At this time, the IP address of the HTTPS request access connection is associated with the domain name to which the HTTPS certificate belongs, that is, the source station IP address of the domain name is found.
It should be noted that, the obtaining of the domain name to which the HTTPS certificate belongs includes: judging whether the domain names to which the HTTPS certificates belong are more than two, if so, marking the domain names to which the HTTPS certificates belong as multiple domain names, wherein the multiple domain names point to the same IP address, and the multiple domain names refer to a plurality of domain names. According to actual requirements, after the domain name to which the HTTPS certificate belongs is marked as a multiple domain name, a decision may be made to discard the multiple domain names or record all the multiple domain names. If a record is made, multiple domain names should be marked for the IP, and typically these multiple domain names will point to the same IP.
In summary, in the embodiment of the present application, the IP address field is accessed through the HTTPS, the return information is obtained, and the HTTPS certificate in the return information includes the domain name to which the HTTPS certificate belongs, so that the relationship between the IP and the domain name is established. The method and the device realize the acquisition of the IP address of the source station, and solve the problems that after a CDN technology is adopted in the prior art, the original program for acquiring the IP address of the access source cannot be normally used, and the acquired program is not the real IP address of the access source but the IP address of a CDN node.
