This article focuses on "how to quickly replace IP with linux". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to replace IP quickly by linux".

Virtual IP is often used when Linux is highly available. Two IP can be configured for a network card on windows, and can be added directly using the ip command in Linux.

Add

Ip address add 192.168.1.200/24 broadcast 192.168.1.255 dev wlp58s0

When adding, you need to specify the mask and broadcast address, so that the machines of the same network segment can receive the broadcast of this address, and you also need to specify which device to add to. Here the wlp58s0 is the name of the network port.

Delete

The deleted command is similar to the added command, only you need to change add to del.

Ip address del 192.168.1.200/24 broadcast 192.168.1.255 dev wlp58s0

Application

When expanding the network segment, we do not want to restart the network card and cause the remote connection to be disconnected. We can first add the expanded network segment, and then delete the original IP and mask.

Ip address add 192.168.1.200/24 broadcast 192.168.1.255 dev wlp58s0ip address add 192.168.1.200/16 broadcast 192.168.255.255 dev wlp58s0ip address del 192.168.1.200/24 broadcast 192.168.1.255 dev wlp58s0

Only three steps are needed to complete the dynamic modification of the network segment, and the remote will not be disconnected at this time.

Summary

None of these operations are saved to the configuration file and are invalidated after restart. Therefore, we need to write our configuration information into the configuration file.
