本文介绍了在Linux系统中查看IP地址的方法。首先解释了IP地址是设备在互联网上收发数据包的标识符，多数互联网服务提供商仍使用IPv4。接着分别阐述了使用ip addr、ifconfig、ip route命令查看IP地址的具体操作。

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.
