When comes to network addressing, IP address plays main role in connecting a system into a network. There are two type of IP addressing, one IPv4 of 32-bit addressing and IPv6 of 128-bit addressing format.
In a company, when all the systems connected to a local server the network addresses are assigned by the DHCP server in-order to save time.
If one wants to know their own IP addressing and of low cost and of more secure, then static IP addressing is preferable. Once assigned, then it becomes constant.
IP address supports Unicast, Multicast, and Broadcast.
