DNS cache sounds like it caches DNS records after a successfull DNS query, right ? The problem at my clients project was, that the DNS server a) wasn't reachable from time to time because they played around with a pix firewall in a cat6k b) these particular OOB IPs and the sun's IPs were not in DNS database So ... I assume a dns *cache* wouldn't have brought any better functionality. We still would have needed a functionality in sshd, to turn off reverse lookup entirely ... The suns have already been secured by firewalls so no real need for this reverse lookup feature.
