What Are Domains?

Domains create your address on the internet. When you own a domain, you can tell people to go to the URL mysite.com and they will see whatever content you’ve associated with that domain. Every domain name is matched to an IP address and follows the Domain Name System (DNS).

Without a domain, every website would only be identified by the IP address. Imagine that instead of typing liquidweb.com into your web browser, you had to remember 67.43.15.214, Liquid Web’s IP address. Now imagine remembering strings of numbers for every website you ever want to visit!


Domain names make it much easier for people to use the internet. It’s the difference between using latitude and longitude to get somewhere and using a street address to get somewhere.

Let’s use support.sivehost.com to show how domain names work. Even though it is a little confusing for most people, domain names are technically read from right to left. No one reads them like this when telling you to visit support.liquidweb.com, of course! But reading from right to left creates a funnel: the address goes from the very general (top-level domain) to the very specific.

Top-Level Domains

Top-level domains (TLDs) like com, net, and org hold the right-most position in a domain name. Every country can have their own TLD, too. Every domain name must end with a TLD. In support.sivehost.com, the TLD is com.
