What is IP or Internet Protocol

Internet Protocol is an address of a Computer on a network. An IP address is a 32 bit address. The IP addresses are unique i.e. no two Computers, connected to the internet can have same IP addresses. IP addresses when started used the concept of classes. This architecture is called class-full addressing. In the mid of 1990s, a new architecture was introduced and was called classless addressing and eventually superseded the original architecture. However, part of the Internet is still using class-full addressing, but the migration is very fast. In classless addressing variable-length blocks are assigned that belong to no class. In this architecture, the entire address space (232 or 4,294,967,296 addresses) is divided into blocks of different sizes. Class-full addressing is a special case of classless addressing.
