Someone mailed me offlist, and said that it wasn't clear what I was
asking in my initial post... I'll try a more terse version:
I want to run a DNS server (named) and dhcpd on my OpenBSD box
(which is the firewall/gateway/router for my home network). I also
want the DNS server to provide name resolution for the
dynamically-addressed hosts in my LAN.
Does the dhcpd that is shipped with OpenBSD 3.7 support the ability
to update bind? Does the dhcpd that is shipped with OpenBSD 3.9
support this? If not, is the recommended approach to install ISC
DHCP 3.x, as suggested by documents such as this:
http://www.bsdguides.org/guides/openbsd/networking/dynamic_dns_dhcp.php
Thanks again,
Matt
