An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there.
Two versions of the Internet Protocol (IP) are in use: IP Version 4 and IP Version 6. Each version defines an IP address differently.
IPv4 uses 32-bit (four-byte) addresses, which limits the address space to 4294967296 (232) addresses. This limitation stimulated the development of IPv6 in the 1990s, which has been in commercial deployment since 2006.
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.
IPv6 uses a 128-bit address, allowing 2128, or approximately 3.4x1038 addresses, or more than 7.9x1028 times as many as IPv4, which uses 32-bit addresses and provides approximately 4.3 billion addresses.
Your IP address will be a number, like 184.108.40.206 or 2002:db7:0:1245:0:567:8:1.
In Windows the IP address can be determined by using the command-line tool ipconfig. In Unix/Linux the command-line ifconfig performs this function.
