I have my primary domain with wildcard subdomains setup already.

username.maindomain.com and maindomain.com

I want to provide my users with additional domains that they can select.

additional1.com, additional2.com, additional3.com...

These additional domains would also need to support wildcard subdomains (as the subdomains route to a username).

Anyone know how to properly configure this in DNS and VirtualHost config?

Currently I have the additional domains as A records pointing to the same IP as my main domain (with a wildcard subdomain A record for each as well). In my VirtualHost config I am placing the additional domain names in the ServerAlias directive.

Let me know if any more detail is needed.


Basically you've already written how to do it:

Create A resource records for example.com and *.example.com, then add ServerAlias example.com *.example.com to the appropriate VirtualHost in your Apache httpd configuration. ServerAlias can occur multiple times inside a VirtualHost container.

  • The issue was in how I was setting up my DNS records. I needed a set of records for each domain, where I was trying to add multiple records for different domains under my primary domain. Mar 7 '10 at 17:18
