may be in the same subnet.  That way, if one of the DHCP servers fail, at least some clients will be
assigned addresses, and you'll already have a second server up and configured for adding another
scope to quickly if the first server is going to be out of commission for awhile.

Sounds pretty makeshift if you ask me.

Set up a couple of servers with free Solaris 10 on them, install free
Sun Cluster on them and then the free HA DHCP and you have yourself a
redundant setup that issues IP's to all clients, not just half. ;)

If you really want to make use of those servers you install free HA
Samba on them and hook up some drives to them and configure them with
ZFS.

The hardware, unfortunately, isn't free, but when was it ever? ;)

Progress isn't made by early risers. It's made by lazy men trying to
find easier ways to do something.
