Domains & DNS, explained simply
Everything you need to know about domain names and DNS — from the basics to email records, transfers, and troubleshooting.
- Difficulty
- Beginner
Your domain name is your address on the internet — and DNS is the system that makes sure people who type that address actually reach your website. This section covers everything from registering a domain to fixing propagation delays, in plain English.
Quick summary
Your domain name (like yourbusiness.com) is registered at a domain registrar. DNS records tell the internet where to send visitors, email, and more. This section explains all of it — start with the basics, then jump to the topic you need.
If you only read three things
- What is a domain name? — the foundation.
- Domain vs hosting vs email — the single most common point of confusion.
- Renewing your domain (don't let it expire!) — the most expensive mistake you can quietly make.
How it all fits together
Almost everything that confuses people about domains, websites and email makes sense once you know the order things happen in. There are four pieces, and they always come in this sequence:
- Your domain — what you own. The name itself,
yourbusiness.com, registered through a registrar for a fixed term. ICANN says that term is typically between one and ten years, and you have to renew before it runs out. Start at What is a domain name?. - DNS — where that name points. A set of instructions attached to your domain, telling the internet which servers to send visitors and email to. Start at What is DNS?.
- Hosting — where your website actually lives. A server holding your site's files. DNS is what connects your domain to it. Start at What is web hosting? and How DNS & hosting fit together.
- Email — a separate service that happens to share the same domain. Your inbox is not on your web host. It is pointed at by different DNS records (MX). Start at Why email & your website are separate.
You can change any one of these four without changing the others — as long as the DNS in the middle is updated correctly. That is why we ask you to tell us before you change anything at your registrar.
