Introduction
There are multiple instances in which you will need to locate the IP address of your Linux server. You can find the private and public IP addresses of your Linux server; it depends on how you are searching. In the article, we will explain the usage of the "ifconfig" command on your Linux Server.
Procedure
Via the command line, you will enter the following:
ifconfig
The system will display all network connections – including connected, disconnected, and virtual. Look for the one labeled UP, BROADCAST, RUNNING, MULTICAST to find your IP address. This lists both IPv4 and IPv6 addresses.
Here is an example of what the output of the ifconfig command will display;
# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1458
