Should allow specification of Private or Public IPs

[jpSimkins]

I see this is adding aliases for both private and public IPs. This is redundant as only one will only be used (the first found). Should be an option to specify what is used on a per alias level.

This will force you to improve the alias system. So I also recommend you do it more as an associative array. The key is the host and then the value are the parameters. This would allow you to assign subdomains on a single host versus having to create one for each and every subdomain.

Something like this would be more useful IMHO

[
   'test.dev' : [
      'subdomains': ['www', 'account1', 'account2'],
      'route': 'private'
   ]
]
