  • Looking at the first octet of an IP address, you can identify the class of that address:

    Class A =1-126
    Class B =128 -191
    Class C =192 -223
    Class D =224 –239
    Class E =240 –254

    Looking at the first octet to determine the class:64.192.29.2 = Class A =64.0.0.0 172.16.32.4 = Class B =172.16.0.0 208.16.14.1 = Class C =208.16.14.0

  • You can check through the first octet of any given IP address, you can identify whether it’s Class A, B or C. If the first octet begins with a 0 bit, that address is Class A. If it begins with bits 10 then that address is a Class B address. If it begins with 110, then it’s a Class C network.

  • Internet Protocol hierarchy contains several classes of IP Addresses to be used efficiently in various situations as per the requirement of hosts per network. Broadly, the IPv4 Addressing system is divided into five classes of IP Addresses. All the five classes are identified by the first octet of IP Address.Looking at the first octet of an IP address, you can identify the class of that address: Class A =1-126 Class B =128 -191 Class C =192 -223 Class D =224 –239 Class E =240 –254.
