A method of private network user access the server in a private network through domain name

Abstract

The disclosed method of visiting private server for user in private network comprises: 1. starting at least the loop interface and address conversion on the device connecting private and public networks, and setting static address conversion for the private server; 2. when recieivng user message from private network, deciding whether the objective IP address is the public IP address relative in private network, yes to step 3, or lese end; and 3. sending message to the loop interface to transmit the message toward private network till the server. This invention makes user in private network eliminate setting DNS server to visit private server.

Description

technical field [0001] The invention relates to a method for accessing a server in a private network, in particular to a method for a user in the private network to access the server in the private network through a domain name. Background technique [0002] Domain Name Server (Domain Name Server, hereinafter referred to as DNS) is a vital part of the Internet. Because computers on the Internet only know IP addresses, but it is very difficult for ordinary people to record a long list of IP addresses, and it is relatively simple to record domain names, so DNS resolution that provides conversion of domain names into IP addresses is set up. [0003] If the external network user wants to access the server in the private network, since there is no public IP in the private network that can be used on the Internet, the domain name entered by the user must be resolved through the DNS server placed on the public network. The address of the corresponding server (public network IP add...

However, if internal users need to access private network servers through domain names, the enterprise also needs to set up DNS domain name servers internally. Otherwise, internal users cannot access private network servers through unified domain names like Internet users, but can only use private network IP addresses. access, which brings a lot of inconvenience to the access of internal users

Setting up the DNS domain name server in the enterprise not only needs to consider the cost factor, but also the networking method becomes complicated; on the other hand, if you do not use the domain name to access the server in the private network but use the IP address to access, it is not as easy to remember and identify as the domain name. For example, calling a person's name is more convenient than calling an ID number, and the user's operability is not strong, and there is no unified access, and the private network IP address is poorly concealed and vulnerable to internal user attacks
