Sometimes it is useful to look up the IP address that you have been assigned through your Internet Service Provider. This would normally be useful when you are looking at your website statistics and you need to know how many of the visitors listed on the statistics are you.
Your Current IP Address: 38.103.63.60
Your Host Address : 38.103.63.60

Internet Protocol - The network layer protocol in the TCP/IP communications protocol suite (the "IP" in TCP/IP). The terms "IP network" and "TCP/IP network" are synonymous. "IP" is generally heard more frequently than "TCP," primarily because it is faster to say IP and also because some data are sent over the unreliable UDP/IP, rather than the reliable TCP/IP. Streaming media, VoIP and videoconferencing typically use UDP/IP because there is insufficient time to check for dropped packets and retransmit them.
Internet Protocol address - The term "IP" is synonymous with "IP address," the four-element number with three decimal points that is the numeric identification of every node in a TCP/IP network. The phrase "what is your IP?" means "what is your IP address?" See IP address.
