That, unfortunately, is not uncommon. Actually, it's one of the _less_ broken systems I've seen, since IPv4 presumably keeps working.
One major vendor of hotel guestnet equipment returns an A record for 0.0.0.1 if you do an ANY or AAAA query for any hostname--even ones that don't exist. At least with WinXP, you have to disable IPv6 just to get IPv4 to work! Worse, their tech support sees nothing wrong with this; if you disagree, all they'll do is offer a refund. Unfortunately, "take your money elsewhere" doesn't work when you've already paid for the hotel room--and they know it.
I've actually extracted significant rebates from Hotels where their internet was provably broken, and, their third-party provider would not resolve the issue. More than just a refund of the IP fees. In one case, 1/2 the cost of my multi-night stay. Owen
