What I remember from a very long time ago is the following network setup: - a collection of NFS servers each with multiple ethernet interface cards connecting to different subnets - a collection of NFS clients that would connect to the first address in the returned RRset (i.e. that would not locally sort the RRset) - a DNS resolver in a completely different subnet that had incomplete knowledge of the network. I think bind treated the 'class B' network as a single network, not as a collection of /24s. Without the sortlist feature the DNS resolver had not enough information to move the best address to the start of the list. And the router was slow enough that you didn't want NFS traffic to go through the router. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
