What's an IP address?
An Internet Protocol address, or IP address, is a unique identifier used by devices on a computer network. The Internet is the largest computer network and there are millions of IP addresses in use on it. It's purpose is to allow other computers on the Internet, or network, to know where you are and how to get data back to you. All domain names, and by extension websites, resolve to an IP address and it's that IP address that your computer uses to find the server that hosts the site you're looking for. Basically, it's a way for computers to find each other, much like a street address for a home.
There are two varieties of IP addresses in use today, IPv4 and IPv6. IPv4 uses a 32 bit number and IPv6 a 128. The address space available for use in IPv4 is depleting rapidly due to the growth of the Internet and is slowly being replaced by IPv6.
IP addresses are binary numbers but are represented in human readable form as either decimal separated numeric strings, such as 22.214.171.124 for IPv4, or colon separated alphanumeric strings, such as 2000:df8:0:4321:0:327:4:54 for IPv6.
