What is Class C IP address?

Answer 1

Class A, B and C Based on the split of the 32 bits, an IP address is either Class A, B or C, the most common of which is Class C. More than two million Class C addresses are assigned, quite often in large blocks to network access providers for use by their customers. The fewest are Class A networks, which are reserved for government agencies and huge companies. Although people identify the class by the first number in the IP address (see table below), a computer identifies class by the first three bits of the IP address (A=0; B=10; C=110). This class system has also been greatly expanded, eliminating the huge disparity in the number of hosts that each class can accommodate (see http://www.answers.com/topic/cider). See http://www.answers.com/topic/private-ip-address-technology and http://www.answers.com/topic/ip-technology.

The host bits are further divided between subnets and hosts. See subnet mask.
