IP address is a unique combination of numbers which separated by full stops and is responsible for identifying each computer using the Internet Protocol to communicate over a network.
There are two ways to set up multiple IP addresses on a computer:
1. If you have multiple network interface cards (NICs) on your computer or laptop then you can easily assign different IP addresses to each card.
2. It is also possible to assign multiple IP addresses to a single NIC.
By default, each network interface card (NIC) has its own IP address and can be checked the serviceability by pinging 127.0.0.1. But as said above, it is also possible to assign multiple IP addresses to a single NIC.
