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.

If you only read three things

  1. What is a domain name?: the foundation.
  2. Domain vs hosting vs email: the single most common point of confusion.
  3. Renewing your domain and turning on auto-renew: 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:

  1. 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?.
  2. 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?.
  3. 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.
  4. 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.

How your domain, hosting, and email connectYour domain name points at DNS settings, which route website visitors to your hosting and email to your mail provider: two separate destinations from one name.A recordMX recordYour domain nameyourbusiness.comDNS settingsthe switchboardWebsite hostingwhere your site's files liveEmail providerwhere your messages live

One name, one set of DNS settings, two entirely separate destinations. Changing your host does not move your email, and changing your email provider does not touch your website.

Read this as text

Your domain name (yourbusiness.com) sits at the top. It points to your DNS settings, which act as a switchboard.

From there the DNS settings send traffic two separate ways. The A record sends website visitors to your website hosting, where your site’s files live. The MX record sends email to your email provider, where your messages live.

The two destinations are independent. They are often different companies, and changing one does not affect the other.

If the four pieces above still feel blurry, read Domain vs hosting vs email. It is the same idea explained with a house-and-mailbox analogy, and it is the single most common thing we get asked about.
