The number of valid IP addresses that can be assigned to a Class C network address is 254. The host number of a Class C address is only 8 digits, and the two IP addresses with host numbers of all 0s and all 1s are generally reserved. A Class C IP address consists of a 3-byte network address and a 1-byte host address.
A maximum of 254 IP addresses can be used in a Class C network.
Analysis:
The host number of a Class C address is only 8 digits, and the two IP addresses with host numbers of all 0s and all 1s are generally reserved.

Class A IP address
A Class A IP address refers to the four numbers in the IP address , the first number is the network number, and the remaining three numbers are the local computer number. If the IP address is represented in binary, the Class A IP address consists of a 1-byte network address and a 3-byte host address. The highest bit of the network address must be "0".
The length of the network identifier in a Class A IP address is 8 bits, and the length of the host identifier is 24 bits. The number of Class A network addresses is small, with 126 networks, and each network can accommodate more than 1,600 hosts. Thousands of units.
Class B IP address
A Class B IP address means that among the four numbers in the IP address, the first two numbers are network numbers. If the IP address is represented in binary, the Class B IP address consists of a 2-byte network address and a 2-byte host address. The highest bit of the network address must be "10".
The length of the network identifier in the Class B IP address is 16 bits, and the length of the host identifier is 16 bits. Class B network addresses are suitable for medium-sized networks. There are 16384 networks, and each network can accommodate The number of computers is more than 60,000.
Class C IP address
A Class C IP address means that among the four numbers in the IP address, the first three numbers are network numbers, and the remaining A number is the number of the local computer. If the IP address is represented in binary, the Class C IP address consists of a 3-byte network address and a 1-byte host address. The highest bit of the network address must be "110".
The length of the network identifier in a Class C IP address is 24 bits, and the length of the host identifier is 8 bits. There are more Class C network addresses, with more than 2.09 million networks. Suitable for small-scale local area networks, each network can only contain up to 254 computers.
Class D IP address
Class D IP address was historically called a multicast address, that is, a multicast address. In Ethernet, a multicast address names a set of stations on the network that should receive a packet. The highest bit of the multicast address must be "1110", ranging from 224.0.0.0 to 239.255.255.255.
