In the current network design ,IP The address mainly consists of A、B、C Three types of differentiation , The first part is after the network , The next one is the host number ．

A class IP Address One A class IP Address by 1 Byte network address and 3 Byte host address composition , The highest bit of the network address must be “0”, Address range 1.0.0.1-126.255.255.254 Usable A There are 126 individual , Every network can hold 1 More than 100 million hosts .

2．B class IP Address One B class IP Address by 2 Byte network address and 2 Byte host address composition , The highest bit of the network address must be “10”, Address range 128.0.0.1-191.255.255.254. Usable B There are 16382 individual , Every network can hold 6 More than ten thousand hosts .

3．C class IP Address One C class IP Address by 3 Byte network address and 1 Byte host address composition , The highest bit of the network address must be “110”. Range 192.0.0.1-223.255.255.254C Class network up to 209 More than a , Every network can hold 254 Host computer .

4．D Class address is used for multicast . D class IP The first byte of the address is “lll0” Start , It's a reserved address . It doesn't point to a specific network , At present, this kind of address is used in multicast . A multicast address is used to address a group of computers at a time , It identifies a group of computers that share the same protocol .

All zeros （“0．0．0．0”） The address corresponds to the current host . whole “1” Of IP Address （“255．255．255．255”） Is the broadcast address of the current subnet .

For example, Chiwang Jiangsu Yangzhou advanced defense BGP line 103.53.125.xxx IP Segment is used for network station construction （ Publishing station 、 A website with a lot of visits ）、 game （steam、 The swim 、 Mobile Games 、csgo、 Dinosaur Island 、 Ark 、 Legend and other large game businesses ）、 Large bandwidth video 、 The live broadcast business is as follows
