Detailed explanation-1: -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.
Detailed explanation-2: -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-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.
Detailed explanation-4: -Class C addresses are used in small local area networks (LANs). Class C allows for approximately 2 million networks by using the first three octets for the network ID. In a class C IP address, the first three bits of the first octet are always 1 1 0.
Detailed explanation-5: -The first byte of a class C network number covers the range 192-223. The second and third each cover the range 1-255. A typical class C address might be 192.5.2.5.
