46. Class D & Class E IP Addressing | Multicasting & Experimental | Computer Networks

We have finally reached the end of the IPv4 spectrum! In this Computer Networks tutorial, we explore the special use cases of Class D and Class E IP Addresses. Unlike Classes A, B, and C, these addresses are not assigned to individual hosts and do not use a standard Subnet Mask. We break down exactly what they are used for and the specific rules you need to know for your exams.

Key Concepts Covered:

Why Class D and E do NOT have Network ID / Host ID divisions.

Class D (Multicasting): Range (224 to 239) and the leading bits rule ('1110').

How Multicasting differs from Unicasting and Broadcasting.

Class E (Experimental/Research): Range (240 to 255) and the leading bits rule ('1111').

Why there is no Default Subnet Mask for Class D and E.

If you are preparing for GATE CS, UGC NET, or university Network Layer exams, this video completes your foundation in IPv4 addressing!
