What a domain name is
A domain name is the readable address people type to reach a site, such as the part after “www.” in a web address. Behind the scenes, computers find each other using numeric addresses. The domain name system, usually shortened to DNS, works like a directory that translates the name you type into the numeric address of the server holding the site.
You do not own a domain forever in the way you own a physical object. You register the right to use it for a set period, commonly one or more years, and you keep that right by renewing it. That detail explains most of the pitfalls described later.
The parts of a name
A domain is read from right to left.
- The extension: the final part, such as the ending after the last dot. Some extensions are general-purpose, some are tied to countries or regions, and others are for particular communities or industries. Some have eligibility rules.
- The main name: the part you choose, to the left of the extension.
- Subdomains: optional extra labels placed before the main name, which let one domain serve several sections or services.
Choosing a name
A name can be changed later, but it is much easier to choose well at the start, because it appears in links, email addresses and printed material. Things worth thinking about:
- Short and easy to say aloud. If you must spell it out every time, people will mistype it.
- Easy to read. Look at how the letters join together. Run-together words can accidentally form other words.
- Limited hyphens and numbers. They are easy to forget or mishear.
- Related to what you do. A name that suggests your topic helps visitors remember it, though a name alone does not decide how a site is found in search.
- Free of someone else’s trademark or brand. Choosing a name that is too close to an established brand can cause disputes and the loss of the name. If you are unsure, ask a qualified professional.
- Suitable for the long term. A name tied too tightly to one narrow offer may become awkward if you broaden your work.
If you are building a portfolio website for your own work, your own name is often a reasonable and lasting choice. You could also check whether matching names are available on the social profiles you plan to use, so your identity is consistent.
How registration works
You register a domain through a registrar, a company authorized to sell and manage names. The general steps are:
- Search for the name you want and see whether it is available.
- Choose the registration period.
- Provide contact details for the registrant, meaning the person or organization that holds the name.
- Pay and confirm your email address if asked.
- Point the name at your site by changing DNS settings, or by following the instructions from your hosting provider or website builder.
Many hosting companies and site builders offer to register the name for you. That is convenient, but check that the domain is registered in your name, with your contact details, and that you can log in to the domain account yourself. Holding the name through someone else’s account, for example a former web designer’s, is a frequent source of trouble when the relationship ends.
Registration usually involves a public record of the registrant’s details. Many registrars offer a privacy option that replaces personal contact information with proxy details. Availability and rules vary by extension, so check what applies to yours.
Renewal and expiry
Renewal is where many sites run into difficulty. Common points:
- Renewal prices can differ from the first-year price, so look at both before you buy.
- Turning on automatic renewal reduces the chance of forgetting, but only works if the payment method on file is still valid.
- Reminder emails go to the contact address on the account. If that address is old or no longer exists, you may never see the warning.
- After a name expires there is typically a grace period, but the exact rules differ between registrars and extensions. During that time the site and any email using the domain may stop working, and recovering the name can cost extra. After further stages, it may be released for anyone to register.
Put the expiry date in your calendar with a reminder well in advance, and keep the contact email and payment information current. For longer-term safety, some owners register for several years at a time, if that suits their budget.
Protecting the domain account
Because a domain controls where your website and email point, losing access to it can be serious. Reasonable steps include:
- A strong, unique password, ideally stored with one of the password managers you already trust.
- Two-factor authentication on the registrar account.
- A recovery email address that you control and check.
- A registrar lock, where offered, which helps prevent unwanted transfers.
- Care with emails claiming that your domain is about to expire or asking you to pay an invoice. Fake renewal notices exist, and following their links can lead to scams. When in doubt, log in to your registrar by typing its address yourself and check the account directly.
Other common pitfalls
- Email depends on the domain. If the name lapses, email addresses at that domain stop working too.
- Look-alike names. Visitors may mistype your name or confuse it with a similar one. Registering a few obvious variations is optional, but consider it if confusion would be costly.
- Mixing up domain, hosting and site builder. They are separate services, even when one company sells all three. The domain is the address, the hosting is where the site’s files live, and the builder is the tool you use to create the pages. Knowing which is which makes problems far easier to diagnose.
- Transfers. Moving a name to another registrar is usually possible after an initial waiting period and involves an authorization code. Do it carefully, and avoid doing it close to the expiry date.
- Buying a previously used name. A name that had a past life may have old links or a poor reputation attached to it. A little checking before purchase is wise.
A short checklist
Register the name in your own account, use accurate contact details, turn on strong account security, note the expiry date, and decide where DNS is managed. Those few steps prevent most of the domain problems that site owners meet, and they fit naturally into the regular upkeep of any live site.
