Given "cat.p.dirtside.com", to argue that "p.dirtside.com" is not a domain of which "cat.p.dirtside.com" is a sub-domain, is to claim, that “cat.p” is a single token. This is no more true than claiming a series of words with spaces can be a single word. It doesn’t matter if I think, want or intend “tooth brush” to be a single word, “tooth brush” is two words with a separator <space> between them. Whereas “toothbrush” is a single word.

Remember my example cat.p.dirtside.com? P.dirtside.com is a subdomain
of dirtside.com. It's an administrative grouping of domain names that
have a particular characteristic. However, p.dirtside.com is NOT a
domain name. It has no DNS records of its own. Only subsidiaries like
cat.p.dirtside.com exist and have DNS records.
Hmm. I would definitely have said “p.dirtside.com" is a subdomain. Hi Dave, I agree that "p.dirtside.com" is a subdomain. Recheck what I said. It's not a domain name, no more so than "sdkflkdfgfsgdfg". That's the contradiction. It gets worse. Is "cat.p.dirtside.com" a subdomain? It's definitely a domain name. You can know it's a subdomain if you find another domain name like abc.cat.p.dirtside.com. But if you don't find another name, how can you as an external observer know that cat.p.dirtside.com is NOT a subdomain?
