Assignment of an IP address

4.1

Structure of an IP address

Address classes
IP address range
1.x.x.x through 126.x.x.x
128.0.x.x through 191.255.x.x
192.0.0.x through 223.255.255.x
224.0.0.0 - 239.255.255.255
240.0.0.0 - 255.255.255.255
An IP address consists of 4 bytes. Each byte is represented in decimal, with a dot separating
it from the previous one. This results in the following structure, where XXX stands for a
number between 0 and 255:
XXX.XXX.XXX.XXX
The IP address is made up of two parts, the network ID and the host ID. This allows different
subnets to be created. Depending on the bytes of the IP address used as the network ID and
those used for the host ID, the IP address can be assigned to a specific address class.
