Question

Vishal Thrivedi · Accepted Answer

TCP/IP defines five classes of IP addresses: class A, B, C, D, and E. Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses from the first three classes (A, B and C) can be used for host addresses. The other two classes are used for other purposes class D for multicast and class E for experimental purposes. CLASS A - 0-127 with a subnet mask of 8 CLASS B- 128-191 with a subnet mask of 16 CLASS C- 192-223 witha subnet mask of 24 For the IP addresses from Class A, the first 8 bits (the first decimal number) represent the network part, while the remaining 24 bits represent the host part. For Class B, the first 16 bits (the first two numbers) represent the network part, while the remaining 16 bits represent the host part. For Class C, the first 24 bits represent the network part, while the remaining 8 bits represent the host part.
