Thanks for the replies, I guess it makes sense for most of you, we have 20 servers, 50 workstations, 40 thin clients, 30 printers and 40 IP phones, so static is easy. We do have 2 additional VLANs, but there are less than 10 devices on each. But I am going to want to do more segmenting. Looks like I will need an additional router.

I know many folks are very adamant about using DHCP, I am wondering why, besides the fact that there is little thought that has to be put into it, what is the advantage? Because when there is a network issue, it is really nice to be able to pin-point the culprit with static addressing. So I don't want to start a religious rant, just hear why people like it so much.

Do hp jetdirects do this as well? Also wondering about whatever network component dell printers use too. Yes, we've had a couple of conflicts so wondering if I should enable the address conflict detection on the dhcp server or leave it alone.
