Convert subdomain to domain name (sub TLD vs TLD)?

It's impossible to this using the DNS (or any other algorithm for that matter) as there's no formal definition of what is a "subdomain".

There is publicly available file describing all sub TLD's located at.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
