What is an IP address?

An IP address, also known as an “IP number” or “IP,” is a code that identifies a particular computer on the Internet. It is made up of numbers with three dots separating them. Every computer, whether it is a web server or the computer you're using right now, requires an IP address/number to connect to the Internet. Your Internet service provider (ISP) will assign you either a static IP address (which is always the same) or a dynamic IP address (which changes every time you log on).
