Detailed explanation-1: -Class C network numbers are appropriate for networks with few hosts–the maximum being 254. A class C network number occupies the first three bytes of an IP address.
Detailed explanation-2: -Class C (192.0. 0.0 to 223.255. 255.255) for general use. Class C addresses have only 8 bits for the host address, limiting the number of devices to 256.
Detailed explanation-3: -Class C networks use a default subnet mask of 255.255.255.0 and have 192-223 as their first octet. The address 192.168.123.132 is a class C address. Its first octet is 192, which is between 192 and 223, inclusive.
Detailed explanation-4: -Class A address can contain the maximum number of 224 (16, 777, 216) host numbers. Class B addresses contain the maximum number of 216 (65, 536) host numbers. And class C contains a maximum number of 28 (256) host numbers.
Detailed explanation-5: -A Class C address consists of a 24-bit network address and an 8-bit local host address. The first three bits in the network address indicate the network class, leaving 21 bits for the actual network address. Therefore, there are 2, 097, 152 possible network addresses and 256 possible local host addresses.
