Again, sorry, should have gone to the list.

Good question. I would assume so, but not sure how/where that gets set, so
possibly not. In the normal course of things, the other 2 seem to get a
reasonable amount of query traffic.

Same subnet, adjacent ip's in fact. Based on previous experience moving ip'=
s
around, there is no significant arp caching or delays. Maybe a few seconds
to a minute. Would this delay be due to caching somewhere else, say root
nameservers? Do they cache at all?

Thanks!
