I have a problem. I have a Debian 7.0 server that resolves non-existent domains (like jhdjkhfkjhsdkjhksjdjkdfbhdfjkdf.com) to his own IP. I know from my Debian-based NAS (and my Mac) that *nix could just say "unknown host" when trying to ping it.
Well, while this does seem like a cosmetic problem at the first try, this is a real problem when something goes wrong. It killed Akismet once as it resolved to itself and got 404 when trying to query.
What's the problem?

imagine the stars in rid****.sajonara.de as rid_d_i_c_k - it gets censored by XenForo, it seems. I was told ridd_ick is a movie with Vin Diesel which is why the server got named ridd_ick. *G*
