Well, the authoritative nameservers for the zone are returning the correct
information, aren't they? As for 172.17.48.57, presumably that's on your own
network -- since it's a private address -- so why don't you ask the admins why
it is resolving incorrectly? It looks like it might be configured with a bogus
wildcard A record.

Everything seems to resolve correctly for me. I think you just have a
misconfigured local server.
