That would require (pardon the pun) domain-specific logic. For most
TLDs (e.g. .com, .org) the domain name is just blah.com, blah.org,
etc. But for ccTLDs, often only second-level registrations are
allowed, e.g. for www.bbc.co.uk, so the main domain name would be
bbc.co.uk I think a few TLDs have even more complicated rules.
I doubt anyone's created a general ready-made solution for this, you'd
have to code it yourself.
To handle the common case, you can cheat and just .split() at the
periods and then slice and rejoin the list of domain parts, ex:
'.'.join(domain.split('.')[-2:])
