Chad, do you have access to the router's config via http or other
interface?? I can only think of two answers. Both involve checking the
router conf. You say that the router doesn't have that capability.....
are you ABSOLUTELY sure?? Before I set up a linux box as my router, I
had a cheapie linksys and the static arrangement was in an obscure
spot. It seems silly that the feature is not there but who knows.
Thinking out loud, if the DHCP range is not .1-.254, even if the router
doesn't have a designated "static" section, you could assign a number
outside the DHCP range. The only other thing I can think of is to
assign a static number to the printer that is in the top of the DHCP
range (like.250) that hopefully will never get auto assigned. This is a
bit risky but it works. I've done it. The risk is reduced if you only
have a few things on the network because the chances of them getting
assigned the static number are obviously less. Most routers assign the
first available number sequentially in my experience. This is definitely
a hack but it's at least it's some kind of solution. You said that the
printers won't take a name so neither of these would bust name
resolution.
