Well, the IP you gave for it does not resolve, as I already showed you--not on my laptop at home, not on my work deskop, and not on my hosted domain. So unless that IP was wrong/irrelevant, that doesn't seem to be true. I can't speak to whatever testing you did but there are potentially a number of reasons why you might get the answer you expect while the rest of the internet doesn't. -- Derek D.
