Network protocol address feedback method and domain name resolution server

Abstract

The invention discloses a network protocol address feedback method and a domain name resolution server. The method comprises the following processing steps: receiving a domain name inquiry request which is sent by a client and carries domain name information, and obtaining one or more network protocol addresses corresponding to the domain name information; checking the health of one more network protocol addresses and obtaining one or more healthy network protocol addresses; and obtaining a final network protocol address from one or more healthy network protocol addresses by adopting load balancing algorithm, and feeding back the final network protocol address to the client. Through the processing, the development amount of heartbeat detection and recurrent selection strategies on a DNS client can be effectively saved and the load balancing of all servers in inquiry records is realized.

Description

Technical field

[0001] The invention relates to the field of communication technology, in particular to a network protocol address feedback method and a domain name resolution server. Background technique

[0002] In related technologies, computers use each other's Internet Protocol (Internet Protocol, referred to as IP) addresses to identify each other. The domain name (Domain Name) is a meaningful name for the network server, for example: www.baidu.com, the domain name server (Domain Name Server, referred to as DNS) stores a large number of network server domain names and their corresponding IP addresses .

[0003] DNS serves as the translation between domain names and IP addresses, figure 1 It is a signaling flowchart of DNS work in the prior art, such as figure 1 As shown, the workflow of DNS includes the following processing:

[0004] Step 1. The DNS client initiates a DNS-A Query Domain Name: www.baidu.com query to the DNS server;

[0005] Step 2. The DNS server receives the q...
