Dynamic allocation is the way to go. Harken back a couple of weeks to our periodic refresh of memories on how MS networking insists upon owning an assigned IP address, willy nilly. It is for that reason I recommend against dynamic assignments. Keep Bind 8 working on that Unix machine. The main EDU network is INW4 and DHCP only for about 500 boxes.

Not often anyone disagrees with Joe for that matter, but I couldn't agree with Richard more on this one. It isnt a perfect world, and we have had more than our share of problems with the Novell bootp servers, but it sure beats the heck out of managing that many statically addressed clients. I run a NetWare and NT-based shop. That hoses the DHCP server. It's a different protocol suite.
