Mapping network printers in DHCP by MAC address

Last Modified: 2012-05-05
Hi! We have a network with 2 DHCP scopes configured for network computers (10.10.10.x and 10.10.11.x). All printers are in the range of 10.10.0.x. For the last several months every now and then (usually once a month) some printers loose their manually configured network settings and drop to DHCP. This problem is kind of obscured and I can't understand the reason why this happens since there seems to be no specific software that could cause this anomaly. So I decided to map all network printers in DHCP.
What is the best practice of doing this? I was thinking about adding a new DHCP scope in the range from to to one of DHCP servers and then make a reservation for printers according to their MAC addresses, but this could also cause that any other domain computers would obtain their IP addresses in that scope once their current lease time expires. So am a bit confused now how to realize it.
What could you advise in this situation? Looking forward to your help! Thank you in advance!
