How to host a dual-line virtual host? Dual-line virtual host means that in the computer room built by service providers, the host supports both Unicom and telecom lines, which completely solves the bottleneck of exchange of visits between telecom and Netcom. Users can choose on demand, but there is no way to operate the virtual host line by themselves.

Dual-line virtual host is suitable for target customers to cover nationwide websites, whether Southern Telecom, North Netcom users and overseas users can quickly access customer websites. There are two key questions about the technical effect of the two-line host, one is the network card and IP working mode, and the other is whether the intelligent resolution of the user's IP address is stable and reliable.

No matter which kind of dual-line, it is necessary to parse the IP address of the user and the server in order to choose the line, so it is very important for IP address resolution technology, equipment and a large address library.

The principle is that when users visit a website, they first query the DNS server for the IP address of the website, and the DNS server will determine whether the user is connected to the Internet by telecom or Netcom. If the telecom goes online, it returns the telecom IP address; if it is Netcom, it returns the Netcom IP address; in this way, it realizes the purpose of intelligent judgment and intelligent identification.

Because this kind of parsing technology has a certain threshold, not every operator can realize it, and only the two-line host with intelligent DNS parsing can be said to be a real two-line service.
