linux如何查看ip地址

What is Ip address?

An IP address is the identifier that enables our device to send or receive data packets across the internet. It holds information related to our location and therefore making devices available for two-way communication.

Most internet service providers still use IPv4. It’s based on 32 binary bits, consists of four numbers from 0 to 255, and is separated by dots. For example, 103.86.98.1.

Check Ip address with ip addr command

ip addr – Show information for all addresses
ip addr show dev em1 – Display information only for device em1

Get Ip address with ifconfig command

The “ifconfig” command is another most common command used to view IP related information.
This command will list all the network interfaces along with their details which include interface status, IP address, MTU size, etc.

Find Ip address with ip route command

The “ip route” command can also be used to find the IP address of a system. In order to find the IP address of a system, use the command as follows:

$ ip route

This command will print out the IP address of our system along with other network details.
