Err, sorry. I meant ‘domain’.
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.
What differentiation are you making between the label “sdkflkdfgfsgdfg” and (say) the label “com”?
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?
I’m unsure what an external observer has to do with this. For me: cat is a sub-domain of p.dirtside.com p and cat.p are sub-domains of dirtside.com dirtside, p, and cat.p are sub-domains of com com, p, cat.p, and cat.p.dirtside are sub-domains of the root. And all are domains. Regards, -drc
