What Is a Domain? A Guide to Picking a Great One for Your Brand

A domain is your site's unique address on the internet, like rgb.ir, showing users and Google a memorable, brandable name instead of a hard to remember numeric IP address.

How does a domain actually work?

When you type a domain into your browser, the DNS system translates that name into the IP address of the server hosting your site. That's why a domain and hosting are two separate but connected things: the domain is the "address," and hosting is the "house" that address points to.

How do you pick a good domain for your brand?

• Short and simple: Short domains are easier to remember and type.
• Relevant to your brand: Ideally the same as your brand name, or close to it, not something completely unrelated.
• No extra hyphens or numbers: These reduce user trust and increase the chance of typos.
• The right extension for your audience: For a local Iranian audience, an .ir domain or .com usually works best; see the full comparison in .ir vs. .com domains.

How many types of domain extensions are there?

Generic extensions (.com, .net, .org) can be registered by any business anywhere in the world. Country code extensions like .ir are specific to each country and typically build more trust and better local SEO with a regional audience.

How long does domain registration take, and what documents do you need?

Registering most international domains (.com, .net, .org, and so on) takes only a few minutes and requires no special documentation. .ir domains typically require a national ID for individuals, or company registration documents for legal entities.

What do you do after choosing a domain?

Once you've registered a domain, you need to connect it to hosting so your actual site can go live. If you don't have hosting yet, look into buying hosting at the same time as registering your domain to get up and running faster.

Bottom line

A good domain is short, relevant to your brand, and uses the right extension. To register a domain with instant search and transparent pricing, check out RGB's domain page.
