【How-to】Why is 255 the highest number in an ip address

As a reference, with 8 bits (each part between dots), you can have 256 different values (from 00000000=0 to 11111111=255). For example, an IP address would be 192.228. 17.57 ( in bits 11000000 11100100 00010001 00111001), representing a C kind address.
