1. What do you mean by classless and classful IP addressing? Explain.

Answer 1

Answer:

Hola..

Here is your answer mate______☺️

Explanation:

Both terms refer to a perspective on the structure of a subnetted IP address. Classless addressing uses a two-part view of IP addresses, and classful addressing has a three-part view. With classful addressing, the address always has an 8-, 16-, or 24-bit network field, based on the Class A, B, and C addressing rules.

Answer 2

Answer:

A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits.
