Question 1

What is classless addressing? Explain distance vector routing with a suitable example

Marks: 10

Chapter: Unit 4: Network Layer (10Hrs.)

Classless Addressing Classless addressing is an IP addressing method where fixed classes (A, B, C) are not used. Instead, it uses CIDR notation (Classless Inter-Domain Routing) in the form IP/prefix.
