above line with '; ' line is a line of comments, there is no practical meaning, it is recommended to write two or more namserver, By default, the first namserver is used to resolve the domain name, and the second is used when the first one is not resolved.2, under the Linux has a special file/etc/hosts can also resolve the domain name, but we need to manually add the ip+ domain name in the content, its role is to temporarily resolve a domain name, ve

set interface address. It should be explained that sin_zero is added to this structure mainly to ensure that the data length of struct sockaddr is the same as that of struct sockaddr_in, so that when using standard functions, you can use a unified data interface. Note that the bzero () function should be used to set all sin_zero to zero. Finally, sin_port and sin_addb must be Network Byte Order ). If "inad

Welcome to the network technology community forum. It is sometimes necessary to interact with 2 million technical staff to enter the Tracking IP address. If your network has problems or you need to change some settings, this is useful. As a network manager, when we solve DHCP faults in Windows, we sometimes need to fin

We have also introduced two DHCP relay faults before. I don't know if you still remember them. If you are not clear about it, You can briefly review it. The DHCP relay fault described here is about the problem that clients of different business types cannot obtain IP addresses of different network segments through relay. DHCP relay failure ◆

Itself is a server, a network cable, need to virtualize multiple ip addresses? The server deployment has the following requirements: Two applications need to be placed on one server. to facilitate management, you need to configure two domain names for them, and DNS is also set up by yourself. In this way, two ip
