I would think that the only way to do it is to maintain a lookup of the
"generic" second level domains under the ccTLDs. For instance:

.co.uk is generic
.bl.uk is not

Wee, how about this one I just found...

www.co.uk

The only way you can tell them apart is to precode that metadata
somewhere.

I smell maintenance nightmare. Tell me again why you want to do this ? I
still don't grok how this code is going to be used.
