URLs are one of the most commonly used technology concepts today. Essentially, they’re the addresses you’d use to access various resources — most of the time, you’re using one to access a particular website available on the internet. Because URLs are “handled” so frequently by users, it’s important to take care when choosing your domain name wisely.
In order for computer networks and servers to “talk to one another,” computers rely on a language made up of numbers and letters called an IP address. Every device that connects to the Internet has a unique IP address and looks something like this:
18.104.22.168 or 3ffe:1900:4545:3:200:f8ff:fe21:67cf
In order to navigate easily around the web, typing in a long IP address isn’t ideal, or realistic, to an online user. This is the reason why domain names were created – to hide IP addresses with something more memorable. You could consider the domain name as a “nickname” to the IP address.
