A domain name is the address used by your audience to find your website.

To better understand what a domain is, think of the internet as a large map of building addresses. If you want anyone to visit or find where you live, you need an address. Just as if you want someone to visit your website, you need a website address. This is your domain name.

You’ve likely heard a number of terms related to domains including domain name, uniform resource locator (URL), web address. You can use these all of these terms interchangeably because they all mean the same thing.

Your website also has an IP address made up of a string of numbers (similar to 104.218.15.162). Instead of requring your visitors to remember that confusing string of numbers to visit you, your visitors can instead just type in your domain name. This is thanks to what is know as the domain name system (DNS).

DNS is simply a group of computers that translates your domain name into your numerical IP address. After all, computers communicate via numbers and not words. How does DNS work? If you want to visit A2 Hosting, all you need to do is remember the domain name “a2hosting.com”. You do not need to know the related IP address made up of the string of numbers. When you type in a2hosting.com into your browser, your request is sent to DNS. DNS looks up the IP address for a2hosting.com and directs you to our website.
