I'd note that DHCP stands for Dynamic Host Configuration Protocol, ,
the keyword here being 'dynamic' , thus,
they are *not* 'static' ip's ;)

The problem here is you have no guarentee they won't change, just the fact
they want to assign them via dhcp hints they may occasionally decide to
rearrange their network...

And you will have annoying problems,,,like not being able to run dns on
the machine (at least, not easily), and a certain vagueness about
authenticating by IP address...

It can set the machine's gateway and interface addresses, if the machine
is only for backup, then , yes, this might squeak by...

Should only require having the init scripts start the dhcpcd daemon in the
network init scripts, dunno offhand if there's a GUI control for it, make
sure you have a serial cable handy, if it fails, you don't have an
ethernet interface ;)

(It's also possible for dhcp to supply other things like the nameservers
of your isp, so you may need to tweak a bit)

ps: make sure they aren't using lame NT dhcp server , if they are, you
have to tell dhcpcd it's obsolete so it will fake something and work
right.

Doing a second IP address on the same ethernet port is more of a project,
and the details depend on the isp, (you may need a hostane or 'client
identifier' so the server can tell the leases apart....)
