Domain name resolution detection method and device, server

technical field

The embodiments of the present invention relate to the technical field of the Internet, in particular to a domain name resolution detection method and device, and a server.

Background technique

In the Internet Protocol (IP) network, the main function of Domain Name Service (DNS) is to convert the domain name (Domain Name) that is easy for people to remember and the IP address that can be recognized by the network. The conversion between domain name and IP address is called domain name resolution, and the network host that performs domain name resolution can be called DNS server. For example, when a client needs to access a website with the domain name www.360.com, it first sends a domain name resolution request containing the domain name to the local DNS server of the Internet Service Provider (ISP) that the client accesses. The DNS server determines the IP address corresponding to the domain name www.360.com through query, and the client connects to the corresponding website server through the IP address.

In order to ensure that the client obtains the fastest access speed when accessing a certain website domain name, usually, the website domain name is directed to the IP address corresponding to the website domain name provided by the ISP accessed by the client. For example, when the client's access ISP is the first network operator, the client can trigger a domain name resolution request when entering a website domain name in the browser, wherein the domain name resolution request includes the input website domain name, and the first network operator The provider's local DNS server directs the website domain name to the first IP address corresponding to the website domain name provided by the first network operator; for another example, when the client's access ISP is the second network operator, the second network operator The provider's local DNS server directs the website domain name to the second IP address corresponding to the website domain name provided by the second network operator.

In order not to affect the client's access to the domain name of the website, in practical applications, when the server on the website side is under maintenance, for example, the server on the website side only opens the IP address corresponding to the domain name provided by the first network operator, and uses the IP address provided by the second network operator. The IP address corresponding to the domain name is cut off. At this time, the user equipment accessed through the second network operator initiates a domain name resolution request, and the local DNS server of the second network operator directs the website domain name to the domain name provided by the first network operator. The first IP address corresponding to the domain name of the website; after the maintenance of the server on the website side, it is necessary to restart the IP address corresponding to the domain name provided by the second network operator, because the DNS server resolves the IP address corresponding to the domain name due to timeliness. In order not to affect the client's access to the domain name of the website, and to ensure that the client obtains the fastest access speed when accessing a certain website domain name, it is necessary to detect the IP address corresponding to the domain name provided by the reopened second network operator.

In the prior art, it is necessary to manually log in to the local DNS server of the second network operator to detect and verify the IP address corresponding to the domain name provided by the second network operator. However, in practical applications, Internet websites provide thousands of Each domain name corresponds to the IP address corresponding to the domain name provided by different network operators. If you need to manually log in to the local DNS servers of different network operators to verify one by one, it will take a lot of time. Therefore, There is a problem of low domain name resolution detection efficiency.
