Are you using OpenSSH? If so, you can disable host lookups. I'm not so sure about commercial SSH.
Anyway, I ran into this problem when servers in our DMZ were taking forever to log into because they were trying to lookup addresses for our internal hosts, which naturally wasn't working. We could have setup /etc/hosts on them, but then we would have provided a map of our internal network in the DMZ. Instead, we just turned off the lookups altogether.
