How many types of IP addresses are there?What is the scope of each category?

There are three segments of private networks and five types of public networks.

Private IP address.

Class A: Class B:

Class C: Class D: Class E:

IP addresses can be divided into five categories: A, B, C, D, and E. The range is the range of the first paragraph.

Class A IP addresses range from 1 127

The Class B IP address range is 128 191

The Class C IP address range is 192 223

The Class D IP address range is 224 239

The Class E IP address range is 240 247

Class IP address. Addresses range from to.

2.Class B IP address. Addresses range from to.

3.Class C IP address. Ranges from to.

4.Class D addresses are used for multicasting.

IP addresses are divided into 5 types according to network IDs: Class A address, Class B address, Class C address, Class D address, and Class E address.

1. Class A IP address: A 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", and the address range is from to. There are 126 Class A networks available, each capable of accommodating more than 100 million hosts.

2. Class B IP address: A 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", and the address range is from to. There are 16,382 Class B networks available, each capable of accommodating more than 60,000 hosts.

3. Class C IP address: A Class C IP address consists of a 3-byte network address and a 1-byte host address, and the highest bit of the network address must be "110". There are more than 2.09 million networks ranging from to class, and each network can accommodate 254 hosts.

4. Class D addresses are used for multicasting:d the first byte of Class IP addresses starts with "LL0", which is a specially reserved address. It does not point to a specific network, and is currently used for multicast.

A multicast address is used to address a group of computers at a time, and it identifies a group of computers that share the same protocol.

5. Class E IP address: start with "llll0" and reserve for future use. All zeros ("The address corresponds to the current host. The IP address of all "1" ("is the broadcast address of the current subnet.

An IP address is a 32-bit binary number that is usually split into 4 "8-bit binary numbers" (i.e. 4 bytes). IP addresses are usually expressed in the form of "dot decimal" in the form of (.
