Domains, subdomains and SSL explained

A domain is your site name, a subdomain sits under someone else's, and SSL shows "Secure". Every plan includes a free subdomain and SSL.

Bai Bua flying on a cloud: your site online with SSL
In 10 seconds
  • Domain = your own site name, such as yourshop.com, billed separately per year
  • Subdomain = yourname.hostinglotus.cloud, free and ready for real use
  • SSL = the "Secure" key. Bua installs and renews it automatically
  • Your own domain works on every paid plan, including one you already own

How do the three differ?

  • Domain: the site name you own, such as yourshop.com. Print it on business cards or your shop sign. Renewed yearly.
  • Subdomain: a name under someone else's domain, such as yourshop.hostinglotus.cloud. Free with every Bua Family account.
  • SSL: the encryption key that makes the browser show a padlock and "Secure" instead of "Not secure". Customers trust it, and Google likes it.

Is the free subdomain good enough for real use?

Yes. yourname.hostinglotus.cloud is a real link with SSL that you can send to customers immediately. It suits the early days, pages shared on LINE or Facebook, or any site where the brand name does not need to be in the URL.

When should I get my own domain?

When you print the address on business cards, signs or ads, and when you want customers to remember and search for your brand. Every paid plan supports your own domain. Registration is billed separately.

Bai BuaAlready own a domain? Just send us the name. The team sends you the DNS settings to enter, and if you get stuck, message us on LINE and we set it up with you until the site says "Secure".

Why does a self-built site say "Not secure"?

Because SSL is missing or incomplete. Doing it yourself means DNS settings, regular renewals and correct server configuration. Bua Family automates all of it. Press Publish and the site shows "Secure" from the first second.

What is DNS, and do I have to set it up?

DNS is the phone book that maps a domain name to a server. On the free subdomain you never touch it. When connecting your own domain, the team sends you the settings to enter and helps on LINE if you get stuck.

Where are the servers, and is my data safe?

In Thailand, so sites load fast for Thai customers. Automatic daily backups. Your data belongs to you and is never sold or shared. See the privacy policy.

FAQ

Common questions

Do I have to buy my domain from Bua Family?

No. If you already own one, connect it free. The team sends you the DNS settings to enter. If you do not have one yet, you can register a new domain through Bua. Domain registration is billed separately.

Can I start on the free subdomain and switch later?

Yes. Start on yourname.hostinglotus.cloud. When you are ready, connect your own domain on any paid plan. Same site, same content, nothing rebuilt.

Do I have to renew SSL myself?

No. Bua Family issues and renews SSL automatically for both the free subdomain and your own domain. Press Publish and the site shows "Secure" from the first second.
