Ok, I used my brain and setup named based on some web refs and the man
pages. Things seem to be resolving nicely now, though I have to go home
and fire up my Mac to see if the initial problem with getting mail and
web services is still around. nslookup, host, arp and netstat all
return quickly without me having to supress name lookups.

Reverse lookups to valid IP address now resolve to the proper hostnames,
and I've set up some PTR and CNAME records for the new hardware and the
usual services. Reverse lookups on IPs w/o hostnames (like my DHCP
range) fail, but they fail quickly w/o going over the wire to my forwarders.

Heck, even lookups on bogus FQDNs fail properly now. W00t.

The dhcpd in 3.1 doesn't support DDNS, so I downloaded and built (in the
interim) the ISC DHCP which does (I wasn't sure if the wide-dhcp port
supported DDNS.) Of course, 3.1 also runs BIND4 which does not seem to
have named.conf so I can set "allow-updates", et al. I can run with an
unaudited third-party dhcpd for now; it isn't listening on any external
device.

I've built BIND9 from ports. Depending on my tests tonight, I may just
leave it be for now. It's there if I need it. Boy, I hope BIND9
understands the old namedb/* files. I'm definitely moving them out of
the way if I actually run "make install".

Perhaps I have a new motto:

"OpenBSD: It's not for children. Though if you like to break your toys,
it might just be for you."
