add 'naked' or 'apex_domain' output.

Sure... uhm, if it were possible or in any way in-scope for the library. This is something that really needs to be solved at the DNS / web server level. Addressable can't really help here.

Hi, sorry, I guess I was not clear enough.

For example say I have some sort of SSL requirement which requires 'www' in my url. (ie I am using EC2 or Heroku).

However, in the case that people are Webfingering my domain, these requests are going to my 'apex' domain.

a = Addressable::URI.parse('https://www.myssldomain.com')
a.authority  #=> www.myssldomain.com
a.host #=> www.myssldomain.com

#what I am trying to propose would be kind of nice

a.apex_domain #=> myssldomain.com

As you mentioned, I realize this is not hard to do by gsubing out the 'www.', but it feels dirty and something Addressable or URI should accomplish, given that Addressable has other nice to haves in the library.

Ok, I see what you mean. That's fair. Low priority at the moment though.

Started thinking about trying to implement this today. After about 15 minutes I realized that this isn't actually possible to build correctly without rather extensive tables of TLDs and second level domains that I'm not inclined to introduce.

uri = Addressable::URI.parse('https://www.example.com/')
uri.zone_apex # => 'example.com'
uri = Addressable::URI.parse('https://www.example.co.ke/')
uri.zone_apex # => 'example.co.ke'

If it could be done with a simple regular expression, that'd be one thing, but as far as I can tell, the zone apex can exist at several different levels depending on where and how the domain was registered.
