What is an IP address? IP stands for internet protocol and is a string of numbers, separated by periods, that is assigned by our Internet Service Provider (ISP). Your IP address is to identify your internet connection. IP addresses are also used for domain names on the web.
There are two types of IP addresses: IPv4 (e.g. 2220.127.116.11) and IPv6 (e.g. 0:0:0:0:0:ffff:d93a:d9ce). IPv6 was introduced due to the internet growing at an exponential rate, we were running out of numbers. With IPv6 it has enabled us to keep expanding, and new IP addresses can be provisioned. With all said, IPv4 addresses are still by far the most common used IPs on the web.
