simplest at times to just make host declarations, but we want the range
for any NEW servers that come in. Because it's during provisioning
stuff, we don't want the IP to change, so we ended up assigning the
first IP they were given by DHCP as their static IP. not a great
system, but not something we wanted to fight with, and it just kept
growing and growing and growing, as hack jobs tend to do :)
I will have to give the reservation a shot - thanks!!

I've never had a problem that way, but then I'm managed my IP's rather
than scattering stuff all over the subnet in a random manner !
I guess that's no help if you've inherited a network from an admin that
just plugged stuff in and let it keep the address it got :-(
Also, if you are in that situation, there is now (I believe) another
option - you can mark a lease as reserved and it will be handled the
same as a dynamic address EXCEPT that it will be kept for use by the
same client and never re-allocated.
