My site does dynamic assignment for all Microsoft OSs on the net 
(around 3000).  We partition the subnet scopes to leave up to the first 
128 addresses at any campus for static addressing.  This is used for 
servers, hubs, routers, and non-MS systems.  We provide backup scopes 
at a central site in the event the local DHCP server goes down (have 
seldom had it kick in, but its there).  With all campuses on DHCP, our 
mobile personnel can plug in an operate w/o problem regardless of 
campus.
We do no active monitoring.  The backup server may provide the lease in 
the event the local server is out of addresses as well, though I don't 
recall ever checking that.
When the address pool was depleted (and it has not occurred in late 
production) our help desk would field the call and net ops address the 
config as needed on a per case basis.  This happened more during early 
rollout in the midst of readdressing the net.

assignment?


I'm curious as to how many sites out there are actually assigning IP 
addresses 
dynamically.  From some of the comments I've seen on the ISC DHCP 
server 
mailing list, it sounds as if many sites are avoiding dynamic 
assignment, and 
opting for nailed up addresses handed out via DHCP.

Perhaps this is done for accountability purposes?  Or perhaps this is a
result of the problematic interactions between DNS and DHCP?  

Have those of you running with dynamic addressing encountered any 
especially
pernicious problems?  Anyone run into the problem of exhausting the 
available
pool of dynamic addresses - how did you discover this problem?  Just 
allowing
people to plug in and turn on would seem to necessitate some kind of 
monitor
to watch for this sort of thing.

Any and all comments in relation to this would be greatly appreciated.

regards,
mb
