I am not suggesting that you assign an IP to the HDHR at all... statically
or using DHCP.  If the HDHR doesn't get a DHCP response, it will pick a
random IP in the 169.254.x.x range (read up on Link Local addresses here:
http://en.wikipedia.org/wiki/Link-local_address)  This is true of most
network devices today to conform with zero configuration networking (
http://en.wikipedia.org/wiki/Zero_configuration_networking).

The advantages of doing this are several:
1. *no* configuration of the HDHR... *at all*... just plug it in
2. you may not need to do any configuration on the server either... depends
upon your distro.
2. no requirement that the server be on before the HDHR... it doesn't care,
it's not using DHCP.
3. no need to worry about your server being connected to your LAN
accidentally and issuing IP's to the rest of the network (done that before
when I confused cables in rats nest on and a test lab dhcp server started
issuing addresses to a~1000 node production LAN... not pretty)

The only disadvantage, as Eric stated, is it will take a minute or so
longer after powering on the HDHR before it is addressable, however I never
turn mine off... so that's what,a minute every few months?
