Comment (by Sebastian):

 When discussing this bug, it was pointed out on IRC that these examples
 that were given in the original report are misconfigured. While the
 reverse dns for these IPs is set, forward entries don't exist. Perhaps
 this is an additional check that onionoo does (and I think it probably
 should do). The host uses hetzner's nameservers, but they can resolve the
 reverse dns just fine.

 The TTL of the entries of those hosts is set to something very
 unreasonably low. If you are in any way responsible for the relays
 mentioned above, please fix their DNS config. This is not to say that
 there isn't a bug still somewhere in onionoo, but afaict, not for the
 hosts mentioned above.
