Um, you're sure that's your hostname?

It's not in DNS.

Um, you're not at [11.22.33.44].

Really? It gives me a timeout and eventually fails.

Well, real information would be useful.

You certainly have a DNS problem, but all your obfuscation just makes it
harder to understand what you're talking about.
