What is a domain name?

A domain name is a human-readable address that points to a location on the internet. Without domain names, every website would need to be accessed by a numeric IP address, which is difficult to remember and share.

This article explains what a domain name is, how the Domain Name System (DNS) translates names into addresses and what you actually own when you register a domain.

What a domain name actually is

A domain name is a reference, not a physical thing. Registering one gives you the right to use that name and control where it points. It does not include a website, email service or any other content. Those are separate services that you associate with the domain through DNS records.

Think of it like a company trademark. The trademark identifies the business by name, but the name itself is separate from the company’s assets. Owning the name does not automatically transfer ownership of anything attached to it.

This distinction matters when you transfer a domain. Moving a domain to a new owner or a new registrar does not automatically move the website or email services associated with it. Those need to be migrated or repointed separately.

How domain registration works

Domain names are managed by a hierarchy of organisations. At the top are registry authorities, each responsible for a specific top-level domain (TLD). For example, all .uk domains are managed by Nominet. Registrars sit below the registry authorities and are authorised to sell and register domain names on behalf of customers.

When you register a domain through Unlimited Web Hosting, we act as your registrar. We handle the registration process with the relevant registry authority and maintain your domain record for as long as you renew it. You can browse available domains using our domain checker.

How DNS connects a domain name to a website

Every server on the internet is identified by a numeric IP address. DNS converts a domain name into the IP address of the server that hosts your website or handles your email. Without this translation, browsers would have no way to locate the correct server from a name alone.

When someone types your domain into a browser, their device queries the DNS system to find the IP address associated with it. That query travels through a chain of DNS servers until it reaches the authoritative nameserver for your domain, which returns the correct address. The browser then connects to that address and loads your site.

Your nameservers control which DNS records are active for your domain. Changing your nameservers points your domain at a different set of DNS records, which is how you move a domain between hosting providers without necessarily transferring the domain registration itself. Our guide on managing nameservers covers this in detail.

DNS changes take time to propagate across the internet. Our guide on checking DNS propagation explains how to monitor this process and what to expect.

Wrapping up

A domain name is a human-readable label that the DNS system translates into an IP address. Registering a domain gives you control over where it points, but the website and email services associated with it are managed separately through DNS records.
