IP address / Internet Protocol address

IP address stands Internet Protocol address and it is an alphanumeric identifier assigned to each device connected to a TCP/IP network like a computer, printer, router, mobile device, etc. It is is used to locate and identify the node in communications with other nodes on the network.

IPv4 (IP version 4) defines an IP address as a 32-bit number and it looks like this: 204.232.239.198. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP addresses was introduced. IPv6 (IP version 6) uses 128 bits for the IP address and it looks like this: 2001:4800:7818:104:be76:4eff:fe05:5f2e.
