Domain Names Explained: Registrar, DNS and Renewals for Business Owners

Your domain name, such as yourbusiness.com.my, is the address of your website and usually your email too. It is one of the most important digital assets a business owns. Yet many owners do not know where it is registered, who controls it or when it expires, often because a former developer or agency set it up years ago.

This guide explains domains in plain language, so you can keep control, avoid outages and work confidently with developers.

Domain, Registrar and Hosting Are Different Things

Three terms often get mixed up:

• Domain name: the address people type, which you rent yearly.
• Registrar: the company where the domain is registered and renewed.
• Hosting: the server where your website files live.

These can all be with different companies. Your domain might be registered with one company, your website hosted with another and your email run by Google Workspace or Microsoft 365. Knowing which company handles which part makes troubleshooting much faster.

Malaysian .my domains, including .com.my, are administered through MYNIC and its resellers. Generic domains like .com are available from many international and local registrars. Some .my domain categories have eligibility requirements, so check the rules when registering.

Make Sure You Own Your Domain

The domain should be registered in your company's name, with contact details you control. A common problem is a domain registered under a developer's personal account or email. If that relationship ends badly, or the person becomes unreachable, recovering the domain can be slow and stressful.

1. Find out which registrar holds your domain. Public lookup tools often show this.
2. Get login access to the registrar account in the company's name.
3. Update the registrant and admin contacts to a company email that does not depend on one person.
4. Store the login details in your company password manager.

Rule: your developer can have access, but your business should own the account.

DNS Records in Plain Language

DNS is the system that connects your domain to services. Common records include:

• A and AAAA records: point your domain to the website server.
• CNAME records: point one name to another, often used for subdomains like www or shop.
• MX records: tell the internet where to deliver your email.
• TXT records: used for email security and verification, such as SPF, DKIM and DMARC.

Changing DNS can take time to update across the internet, and a wrong change can take your email or website offline. Ask your developer to note every change and keep a copy of current records before editing. For email security records, see our guide on SPF, DKIM and DMARC.

Never Let It Expire

An expired domain means your website and email stop working, sometimes on the busiest day of the year. Worse, after a grace period, someone else may register it. Turn on auto-renewal, keep a valid payment card on the registrar account and make sure renewal reminders go to an inbox someone reads.

Consider renewing for several years at a time for your main domain. Also register common variations, such as both .com and .com.my, if they matter to your brand, and redirect them to your main site.

Be wary of emails warning that your domain is expiring that come from unknown companies. Some are scams or aggressive offers to transfer your domain. Always check renewal status directly in your registrar account.

Keep a screenshot of your DNS records somewhere safe.

Working With Developers and Agencies

When starting a new website project, give developers DNS access or a delegated user rather than your main registrar password where the registrar supports it. Ask for a short handover note listing what was changed. Our post on documentation your future freelancer will thank you for explains what that note should contain.

If you are moving hosts, plan DNS changes for a quiet time and lower record TTL values in advance if your developer recommends it, so changes take effect faster. Keep the old hosting active until the new site and email are confirmed working.

At the end of any project, ask for confirmation that your registrar account is still in your control and that no unexpected records were added.

FAQ

Should I choose .com or .com.my?

Many Malaysian businesses use .com.my for local trust and also hold the .com if available. Pick one as the main address and redirect the other.

Can I move my domain to another registrar?

Yes. Domain transfers are common. You usually need an unlock and an authorisation code from your current registrar.

Does my domain include email?

No. Email needs a separate service, such as Google Workspace, Microsoft 365 or your host's email, connected through DNS.

Your domain is a core business asset. Know where it is registered, make sure the company owns the account, understand the basic DNS records, keep auto-renewal on and give developers access without giving away ownership.
