Very true, and we leveraged that fact back at C&C. Everything that
wasn't a server was DHCP, with statically assigned addresses. This
vastly simplified work when network changes were rolled out, because
we could simply adjust the servers and then all the network clients
would pick up the change either at the next lease renewal or reboot.
Made migrating to new DNS, WINS (yek), NTP, and other servers (and
routers) much less painful. You can actually send a lot of
information to a DHCP client. (Whether the clients listen is another
issue. *cough*windows*cough*)
So what is wrong with DHCP?
DHCP as implemented in just about every single NAT/firewall/router
box you can buy these days only allows ephemeral IP addresses. A few
may allow you to statically assign an address based on MAC of the
client, but I haven't seen these with my own eyes.
I'm assuming it's the "DHCP means ephemeral IP addresses" that he's
balking at.
