How to Configure DHCP to reserve IP range based on MAC address ran

Hello,

I am configuring a DHCP scope on a Windows 2003 server. We are installing
IP phones in our network, and they all start with the same 5 characters in
their MAC address. I want to configure the DHCP server to reserve a range of
IPs that is linked to the range of MAC addresses that the phones use. I've
done some googling and looking around in the DHCP settings, and can't find
any way to set a MAC Range reservation. It's easy enough to reserve a single
client MAC, but to make a range of MAC addresses pull from a specific pool of
addresses seems impossible with Win 2k3. Anybody have any ideas or know of a
setting/registry hack/3rd party application that can do this? Thanks!

You can't reserve MAC addresses by range. Can you clarify why you need to
specify by MAC range?

For management purposes, mostly. I want to be able to look at a device IP
and know that it is a VoIP phone. Or make sure that the phones are limited
to a specific number of IPs, or apply any DHCP settings to just the phones.

It isn't worth the trouble. Just statically configure the phones and be done
with it,..don't even use DHCP to begin with. If you use DHCP you will have
to "reserve" then individually one at a time. If you statically configure
them, then you only have to create one Exclusion range in DHCP and you're
done.

Agreed.
