    That is no longer an option.  Many of our devices in the building 
were installed and are supported by third party vendors who have, at 
time of installation, configured their applications to work based on 
those IPs.  Consequently, we have devices with static IPs that are 
scattered all over the spectrum.  I can't change them and clump them all 
together in a range without going through some serious pain, contacting 
each vendor and have them send a technician to come "fix" the issue.  I 
need to work with what's currently there.

    We go through client computers faster than we do our larger 
equipment.  We have clients who walk in the building wanting to get onto 
our network.  I'm not there every time, and without me in the building, 
it's a guessing game for them to figure out what IP they can use to get 
on.  Let alone having to figure out how to even set a static IP and 
proper routing on our network.  Most laptops you buy nowadays are, by 
default, configured for DHCP.  Most routers you buy, is configured for 
DHCP, so most people don't bother with any networking, or to figure out 
how to actually change their settings.  So, it makes more sense, for us, 
a service bureau, to convert part of our network to DHCP for our 
clients.  I just need to figure out how to do it while retaining the 
static IPs that are required, and converting everything else to DHCP and 
call it a day.
