The last part was the country or top level domain (like com or org).

If there is only 2 parts, its easy to say that the other is the company (or "entity" if you prefer).

But If you dont know exactly the meaning of the other parts,
you are out of luck...

In Canada, you can have a canadian domain (domain.CA), or a provincial domain (domain.QC.CA) or city domain (domain.MTL.QC.CA).
But also your company can have subdomains like hr.domain.qc.ca and so on.

You can only know for the last part. Thats it :-)
