What is an IP address?
“IP address” stands for Internet Protocol address, and each device that is connected to a network (like the internet) has one.
An IP address is similar to your phone number. Your phone number is a unique set of numbers that identifies your phone so that other people can call you. Similarly, an IP address is a unique set of numbers that identifies your computer so that it can send and receive data with other computers.
Currently, most IP addresses consist of four sets of numbers, each separated by a period. 192.168.1.42 is an example of an IP address.
An IP address can either be dynamic or static. Dynamic IP addresses are temporarily assigned each time your computer connects to a network. Static IP addresses are fixed, and do not change. Dynamic IP addresses are more common that static addresses — static addresses are typically only used when there is a special need for them, such as in the administration of a server.
