This doesn't work outside of the US. For example, companies in the UK
tend to have domain names that end in .co.uk. I don't know if you can
tell merely by syntax what the actual domain of authority is for a DNS
name.
Is this a necessary feature? If it isn't reliable and can be abused,
it would be best to avoid it.
