1. In Windows, you can use CMD to enter ipconfig or set interface to view the IPv4 address, subnet mask and default gateway; 2. Mac users can use the ifconfig command in the terminal or view TCP/IP information through network preference settings; 3. Under Linux, you can use the ip a or ifconfig command to view the interface configuration, and some systems need to install the net-tools package. Different systems can obtain IP address and network interface information through graphical interfaces or command lines, and can be completed quickly after familiarizing with the operation.

Want to know how to check your IP address and network interface configuration? Actually, this is not difficult, but many people may be a little confused when they first operate it. Next, I will divide it into several steps to talk about how to quickly find this information under different systems.

How to check IP and network interfaces in Windows system?

If you are using a Windows computer, the easiest way is to use the command prompt (CMD) or the settings interface to view:

• Open the "Start Menu", enter cmd , and enter
• Enter ipconfig in the command line and then see the output result
• You will see the IPv4 address, subnet mask, default gateway and other information.

In addition, you can also view it through the graphical interface:

• Open Settings → Network and Internet → Status
• Pull down and click "View Network Properties" to see the detailed information of the current connection

Note: Sometimes there may be multiple network adapters, such as wireless network cards and wired network cards. Remember to make sure you are looking at the one you are currently using.

How to check network configuration on Mac system?

Mac users can view it through terminal or system preference settings:

Terminal method:

• Open "Terminal" (can search in Spotlight)
• Enter ifconfig or networksetup -getinfo Wi-Fi
• Check the information of the corresponding interface, such as en0 or Wi-Fi

Graphic interface method:

• Click the Wi-Fi icon in the upper right corner and select "Open Network Preferences"
• Click the currently connected network, then click "Advanced", and there will be detailed TCP/IP information in it.

Tips: If you are using a company or school network, the IPv6 address will sometimes be displayed. Remember to pay attention to the IPv4 part, because most of the time it is still mainly IPv4.

How to view IP and interface information on Linux systems?

Linux users are generally more accustomed to using command-line tools. The two common commands are:

• ip a or ip addr show - you can see the status of all network interfaces
• ifconfig —— This command may not be installed by default in some distributions, and the net-tools package is required

For example, if you want to know the IP address of the eth0 interface, you can enter:

 ip addr show eth0

You can see the corresponding IP address, broadcast address, subnet mask and other information.

In addition, if you want to view the routing table, you can use:

 ip route show

If it is a server environment, it is recommended to check out configuration files such as /etc/network/interfaces or /etc/sysconfig/network-scripts/ifcfg-* to understand the static configuration of the interface.

Basically these are the methods. Whether it is troubleshooting network problems or setting up remote connections, figuring out your own IP and interface configuration is the first step. Different systems are slightly different, but the core logic is similar, and you can get it done in a few minutes after you get familiar with it.
