How do I set Linux to obtain IP automatically?

In a Linux system, you can change the network configuration file to set the IP to automatically obtain. The specific steps are as follows:

1. Open the terminal.
2. Edit the /etc/network/interfaces file with superuser permissions using the vi editor.
3. Locate the line in the file corresponding to the network interface you want to change. Typically, lines starting with “iface” will be followed by the name of the network interface, such as eth0 or wlan0.
4. Dynamic Host Configuration Protocol
5. Save the file and exit the editor.
6. Please restart the networking service using sudo.

After completing the above steps, the system will attempt to automatically obtain an IP address through the DHCP protocol.
