Addon domains are domains that are pointed to subdomains. This means that you can host multiple domains, with different content, in a single web hosting account.

An add-on domain makes it possible for you to have an additional website (with email) on just one account. The Basic plans come with 1 free add-on domain.
You can have up to 10 add-on domains per account with the Basic plan.

After your first free add-on domain, additional add-on domains can be purchased for 80 baht per month.
