Internet Protocol (IP) Principle protocol for attempting to send data between two computers Each device has an IP address
Internet Protocol (IP) The first major version of IP, now referred to as Internet Protocol Version 4 (IPv4) is the dominant protocol of the Internet, although the successor, Internet Protocol Version 6 (IPv6) is in active, growing deployment worldwide. While IPv4 allows 32 bits for an IP address, and can therefore support 232 (4,294,967,296) addresses, IPv6 uses 128-bit addresses, so the new address space supports 2128 (approximately 340 undecillion or 3.4×1038) addresses.
