IP address - Definition from the Hotspot Shield Glossary

An IP address (Internet Protocol) is a method of identification for any device connected to a TCP/IP network. An IP address works much in the same way as your home address in that data and messages can be transferred to a device using the IP address, like mail can be delivered to your house using your zip code.

An IP address is split into four segments separated by periods, each segment contains a single number between 0 to 255 - This address (defined by IPv4) is considered a 32 bit address - An example of a 32bit IP address could be As there are only a limited amount of possible IP addresses, IPv6 introduces a 128bit IP address which allows for a much greater amount of potential address variations. To find your IP address you can use the ipconfig command in the command prompt on windows computers, alternatively you can search Google!
