What is Classful addressing?

networking

Solution 1:

If you want to know about networks, then given that you asked the question, you'd probably want to know about IPs Addresses and related topics - IP addressing schemes, subnetting.. And you'd want to know about Routing - particularly IP Routing.

Nowadays CIDR is used, as you probably know, that's Classless addressing rather than classful, hence you ask your question..

It is still worth knowing classful addressing, if you want to know CIDR, since it will help you to understand the need for CIDR. Also, sometimes people still use the terminology of classful addressing. Furthermore, learning classful addressing is trivial compared to learning CIDR, and will not get in the way, and may even help.
