SUMMARY: Quick DHCP Setup

This was one of those silly things that I would have never figured
out in a million years if Dave Miner had not asked about it. Despite
filling in netmasks in dhcpmgr(1M) dialogs, in.dhcpd(1M) (and
dhcpmgr(1M) too) actually need netmask information in the netmasks(4)
file in order to work properly. Once I added,

	172.18.0.0	255.255.255.0

That is tell them that I'm breaking this Class B space into /24
networks, things worked a lot more smoothly. (Well, after I re-entered
everything into dhcpmgr since it killed all of my data for
172.18.245.0/24 when I removed the extra 172.18.0.0 entry).

Thanks to the others who responded as well.
