What is dual line dual IP? As we all know, the bandwidth in the south is mainly telecommunications, while that in the north is mainly China Unicom. To achieve interconnection between the north and the south, it is necessary to use dual line server hosting. Currently, there are two types of dual line server hosting, namely dual line IP The server Custody and BGP So what is a dual line dual IP server? Neutrino network Today, I will show you some simple and understandable expressions.
The dual network cable implementation method is to install two network cards on a server, access the telecommunications network cable and the Netcom network cable respectively, and set a Netcom IP and a telecommunications IP, so that a server has two IP addresses, so that the routing table of Netcom or Telecom is added on the server, so that Netcom users and telecommunications users can access from different lines. There are two common ways to use dual IP dual lines:
1. The administrator sets two links with different IP addresses on the website. Netcom users click Netcom IP to enter the server, and telecom users click Telecom IP to enter the server.
2. Using the function of DNS server software to return different server IPs for different IP address requests, it realizes the return of Netcom IPs when Netcom users request domain names, and the return of telecom IPs when telecom users request domain names, which is the intelligent DNS scheme proposed by IDC.
Two IP two line access
"Dual IP and dual line access" improves the speed of Netcom and Telecom users accessing websites to some extent, but its disadvantage is that the dual network card accessed by the server must set a routing table on the server, which increases the difficulty of maintenance for ordinary users, and all data packets need to be routed on the server and sent to different network cards, Server resource consumption is high. It is relatively simple to solve the double line problem, but the disadvantage is that the stability is not enough and the maintenance is a bit complicated. This scheme is usually adopted by small websites or game services.
