The format of an IPv4 address is also called a dotted-quad sequence. It is represented as: a.b.c.d , where a and d are numbers from 1 to 254 and b and c are numbers from 0 to 255.
IPv4 address consists of 4 bytes identified as abcd. Bytes a and d are numbers from 1 to 254 and b and c are numbers from 0 to 255. The computer processes IP addresses as raw bytes. To make it human readable, the dotted-quad sequence is introduced which interprets the address as: a.b.c.d
