What is a dual-line virtual host in China? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The domestic dual-line virtual host means that the same server has two lines of telecom network and Netcom network at the same time. Through routing intelligent judgment of users'IP address, telecom users can access telecom lines when visiting websites, and Netcom users visit Netcom lines when visiting websites, so as to achieve the purpose of mutual visit between the north and the south.

What is the dual-line virtual host in China? The so-called two-line virtual host, also known as intelligent two-line virtual host and intelligent two-line website space, is an intelligent two-line virtual host service specially launched to solve the problem of interconnection between southern and northern telecom and Netcom users.

From the classification point of view, the two-line virtual host includes three types: single IP address single network card, double IP address single network card and double IP address double network card. The single network card double IP and the double network card double IP both have a telecom IP address and a Netcom IP address. Telecom users access telecom IP address, and Netcom users access Netcom IP address. Only in this way can telecom Netcom access quickly.

The biggest advantage of dual-line virtual host is that the access speed of both telecom and Unicom lines can be relatively fast. fundamentally solve or reduce all kinds of direct or indirect economic losses caused by the loss of website information visitors or customers caused by network congestion. There is no big difference in the speed at which our website opens in the north and south, so as to achieve a good user experience.

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 route, so the IP address resolution technology, equipment and a perfect and huge address library are very important-the principle is that when users visit the website, they first query the IP address of the website to the DNS server, 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.

This is the end of the answer to the question about what is a dual-line virtual host in China. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
