What is an IP address?

An IP (or internet Protocol) address is the numerical identifier for a computer on the internet. IP addresses are generally written as a string of digits punctuated by dots or colons as in 172.16.254.1 (IPv4), and 2001:db8:0:1234:0:567:8:1 (IPv6). IP addresses are often linked to geographic areas, allowing a website to identify the country and/or city from which a user is accessing the site.

How does an IP address work?

Any device that connects to the internet is assigned an IP address. See also DHCP. This IP address is often used by websites and other web services to help identify users, although a user’s IP address can change if they connect from a different location, device, or if they use a VPN.

IPv4 was long the standard type of address assigned to a device, but due to the fast growing number of connected devices, the number of IPv4 addresses is soon running out. IPv6 was created to solve this problem, as it offers a much larger range of addresses, but adoption has been hampered by compatibility issues and general laziness.
