Suggestions:
 - "host" does DNS lookups, but is your system's nsswitch.conf or
equivalent actually configured to use DNS?
 - have you turned off DNS lookups in sshd with "UseDNS no" in sshd_config?
 - you could try setting "HostbasedUsesNameFromPacketOnly yes" in sshd_config.

usually comes from bad judgement.
