MAC addresses, hostnames, and DHCP

[Drew Van Zandt]

You can assign multiple IPs to one DNS name, though I believe it uses
round-robin by default, so half the time it'd get a "can't contact" by
name.  I suppose you could use iptables to forward the not-in-use IP to the
in-use one (by adding that IP to the server's interface, e.g. eth0.1) or
update the DNS to point the hostname to the active IP... doesn't the DHCP
server allow you to call an external program at some point?  perl script.
