Which command can be used on Linux and MAC hosts to get IP addressing information?

To retrieve IP addressing information on Linux and macOS hosts, the command that can be used is:

ifconfig

or, for more recent systems, you might also use:

ip addr show

Explanation:

1. ifconfig: This command displays information about all active network interfaces, including IP addresses, netmasks, and broadcast addresses. However, on some modern Linux distributions, ifconfig may not be installed by default since it is being phased out in favor of the ip command.

2. ip addr show: This command is part of the iproute2 package and provides detailed information about network interfaces, including their IP addresses (both IPv4 and IPv6). It offers more functionality compared to ifconfig.

You can run either command in the terminal to get the required IP addressing information for your network interfaces.
