How to Register a Domain 2026: Name, Where & Cost

What is a domain

A domain is your website name (e.g. example.com) that people type into a browser to reach your site. Behind the scenes, the domain is translated into the server's IP number through the DNS system, so people can remember a name instead of digits. A domain is your brand's first digital asset and a permanent address used for both the website and email.

This guide covers everything from choosing a name, picking an extension, the actual registration steps, setting up DNS, enabling privacy, through to renewal and transferring a domain between providers — written so a beginner can follow along in 2026.

How to choose a name

A good domain name is easy to remember and easy to share. Recommended principles:

• Short and memorable — the shorter the better, no more than 2-3 words
• Easy to spell — type it correctly the moment you hear it
• Related to the brand — reflects the business name or what you do
• Avoid hyphens and numbers — they are hard to say aloud and easy to mistype
• Check trademarks — avoid names that clash with other brands to prevent legal issues

Before deciding, prepare 2-3 backup names, as popular names are often taken, and search the name on Google to ensure it does not clash with another confusingly similar business. Something many overlook: say the name aloud to someone and have them type it — if they mistype it often, the name is too hard to remember.

Avoid names tied to a temporary trend or a year, because a domain is a long-term asset; a name reflecting your brand's core identity lasts longer. If possible, also check that the matching social-media handle is still available, so your brand is consistent across every channel.

Choosing an extension (.com / .co.th)

The domain extension (TLD) affects image and target audience. Popular choices in Thailand:

• .com — global, most popular, suits everything; pick it first if available
• .co.th — registered Thai businesses (requires documents), adds local credibility
• .in.th — general individuals or organisations in Thailand, easier to register than .co.th
• .net / .org — alternatives when .com is taken, or for organisations

If budget allows, many brands register multiple extensions (e.g. .com + .co.th) to keep competitors or bad actors from registering a similar name, then redirect them all to the main domain.

Where to register

You can register a domain directly through a registrar, or through a hosting provider that also sells domains. The advantage of registering in the same place as your hosting is managing DNS, renewals, and invoices in one account, reducing hassle.

What to look for when choosing a domain provider: transparent renewal pricing, an easy-to-use DNS management system, WHOIS Privacy support, and responsive support. Providers like AsiaGB offer both domains and hosting along with the DirectAdmin control panel to manage DNS in one place.

Step-by-step registration

Once you have chosen a name and provider, the actual registration goes like this:

1. Use a domain search box to check the name is still available
2. Add the domain to the cart and choose the registration period (starts at 1 year)
3. Enter accurate, truthful registrant details
4. Choose to enable WHOIS Privacy and auto-renew
5. Pay and wait for the system to activate the domain (often within minutes)
6. Go to the DNS management page to point the domain to your hosting

For .co.th there is an extra step: you must upload business registration documents and wait for staff to verify before activation, which may take 1-2 business days.

Pricing and renewal

.com costs around a few hundred baht per year, depending on the registrar and promotions. Points to watch:

• The first-year price is often a promotion, but the renewal price may be higher
• Check the renewal price before deciding, not just the first-year price
• Registering several years ahead locks in the price and reduces the risk of forgetting to renew
• .co.th is usually slightly more expensive than .com due to document verification

Registering multiple years ahead or enabling auto-renew helps prevent losing the domain, which is hard to fix afterwards. In addition, some premium domains (short or popular words) can cost far more than usual because they are pre-valued, so always check the price before deciding.

In short, when comparing domain prices, always look at three numbers: the first-year price, the renewal price, and any hidden fees (e.g. WHOIS Privacy, which some charge extra for and others include free), to see the real long-term cost.

Setting up DNS after registration

After registration, you must set up DNS to point the domain to the servers hosting your website and email. Key records to know:

• A record — points the domain to the web server's IP number
• CNAME — points a subdomain (e.g. www) to another name
• MX record — defines the mail server that receives the domain's email
• TXT record — used for ownership verification and SPF/DKIM to prevent email spoofing
• NS record — specifies the nameservers managing the domain's DNS

If you register the domain with the same host, the system usually sets the A record automatically. But if registered elsewhere, you must change the nameservers to point to your host. DNS changes take time to propagate, from a few minutes up to 24-48 hours. During this window some users may still see the old site because DNS values are cached, so do not panic if the site does not appear immediately.

A tip for your first DNS setup: set records for both the root domain (e.g. example.com) and the www subdomain pointing to the same place, so users can reach it either way. And if you use an email service separate from your hosting, do not forget to set the MX record correctly, or email will not be delivered.

WHOIS privacy and security

A registrant's details are recorded in the public WHOIS database, which anyone can look up. Enabling WHOIS Privacy hides your name, email, phone, and address, replacing them with the provider's details, helping reduce spam and nuisance sales calls.

Beyond privacy, secure your domain account by:

• Enabling Registrar Lock (Domain Lock) to prevent unauthorized transfers
• Enabling 2FA on your registrar account
• Using a secure, always-accessible email as the registrant email

Renewal and avoiding expiry

An expired domain is a common problem that takes the website and email down immediately. To prevent it:

• Enable auto-renew and verify the card/payment method still works
• Use an email you check regularly for renewal notifications
• Note the expiry date in your calendar

If a domain expires, there is still a grace period to renew normally, followed by a redemption period that allows renewal but with high fees, and after all of that the domain is released for others to register. So never let it lapse.

Transferring a domain

If you want to move a domain to another registrar (e.g. to consolidate management or get a better price), the main steps are:

1. Unlock the Registrar Lock at the current provider
2. Request the EPP/Auth Code (transfer authorization code)
3. Start the transfer request at the new provider and enter the EPP Code
4. Confirm the transfer via the registrant email

The transfer process usually takes 5-7 days and requires the domain to have been registered for at least 60 days. A transfer often includes an additional 1-year renewal in the transfer fee. Transfer well ahead of the expiry date to avoid risk.
