What exactly is your nameserver looking for when it's causing these
dial-ups? Is it calling the internic root-servers, doing axfr's from some
other host, etc....? Got a snippet of a sniffer log you could post?

I thought about that, but wouldn't that pretty much kill the name lookups?
I
mean, if a name wasn't cached, then the lookup by named wouldn't unless the
modem-link was already established since ppp wouldn't auto-dial out on a 53
packet. Or did I miss something here?
