addon domain

An addon domain is the surface for “the customer bought a second domain and wants it on the same hosting”. Different from a subdomain (which is a name beneath an existing domain like blog.ablemoose.example) and different from a separate ApisCP account (which would have its own login and quota envelope).

In Able Moose’s case: the firm registers ablebookkeeping.example as a secondary domain. From their end-user panel, DNS > Addon Domains adds it under the same account. The customer logs in with the same credentials, the second domain shares the same disk and bandwidth quota, and DNS / mail / web for the new domain can be managed alongside the primary ablemoose.example. Each addon domain typically gets its own document root (/var/www/<domain>) to avoid .htaccess collisions with the primary site.
