Domain Name vs Web Hosting: What Each One Does for a Small Business

A new café owner buys a website address on a Tuesday, types it into a browser on Wednesday and sees a parking page with someone else's adverts. Nothing is broken. The address exists, but there is nothing behind it yet, because a domain name and web hosting are two separate things that happen to be sold side by side.

The short version

• A domain name is the address people type, such as a shop's name followed by .com or a country ending. You rent it from a registrar, usually by the year.
• Web hosting is space on a server, a computer that stays switched on and connected, where the website's files and database live and from which pages are sent to visitors.
• DNS is the directory that joins the two. Records attached to the domain tell browsers which server to ask for the site and tell other mail servers where to deliver email.

You need both for a working website. You can own a domain without hosting (it simply shows nothing or a placeholder) and you can have hosting without a domain of your own (the site then sits at an awkward address supplied by the host).

Side by side

Buy them together or separately?

Bundles are convenient: one bill, one login, and the DNS is set up for you. Keeping them apart has its own logic. If the domain sits with a registrar and the site sits with a host, a falling-out with the host means changing a few DNS records rather than prying the address loose at the same time as the files. Many small businesses start with a bundle and separate the two later once the site matters more.

Whichever route you choose, the hosting side deserves the closer look, because that is where speed, backups and support live. The checklist in four factors for choosing a business hosting provider covers what to ask before signing, and businesses whose customers are mostly in one country will find the local angle in choosing a web host in Australia, where server location and support hours get their own section.

Where email fits in

Email at your own domain is a third piece that often gets tangled up with the other two. The mailboxes might be included with the hosting plan, sold by the registrar, or run by a separate email service. In every case, DNS records on the domain point incoming mail to the right place and publish the rules that stop strangers sending mail in your name. When a business moves its website, those mail records are the ones most often forgotten, and email quietly stops arriving.

Mistakes that cause the most trouble

1. The domain is registered to the web designer, not the business. Check the registrant name in your registrar account. If someone else owns the address, they control it.
2. Renewal reminders go to an old address. Make sure the contact email on the domain is one that is read, and turn on auto-renew.
3. Nobody knows the login. Store the registrar and hosting logins in the business password manager, with two-step sign-in switched on.
4. The site is moved but DNS is not. New hosting does nothing until the domain's records point to it, and changes can take some time to reach every network.
5. Cheap first year, expensive second. Both domains and hosting often have introductory prices; note the renewal price before you commit.

Where cloud services come in

Shared hosting is only one way to run a site. Larger shops and web apps often sit on cloud platforms that spread the work across many machines and bill by use. The trade-offs are similar to those for any business system moving off a local server, discussed in cloud-based computer systems. For a brochure site or a small shop, though, a plain hosting plan and a well-looked-after domain remain the simplest combination.
