DHCP servers and MAC addresses

[Danny]

Is it possible to set DHCP to dynamically assign IP address only for MAC
addresses that have been registered? (ie. If the MAC address isn't
registered, they don't get an IP)

Not that I know of.

If this is what you are looking for use a bootp server, not DHCP.

The DHCP Server is designed so that you DO NOT have to manually
register MAC Addresses.

Sure.

Exclude the whole range from the DHCP allocations, and then just reserve
the IP addresses you want to allocate.

Dead easy, actually.

Yes, this is possible. This is how our dhcp server (netware 4.11) is set
up. You just create a subnet profile with the relevant subnet info and
where it says "automatic ip address assignment", select "no".

Then create a workstation and assign the IP for that subnet and mac
address. If you have lots of workstations you will there all day
creating workstation. The alternative (which is what I do) is to create
a dhcptab file (in the sys:\etc directory) with all workstations and
their relevant info. Took me time to figure this one out as this is not
documented. I have written code to create this file from an ms access
database. Makes life much simpler as I have to update workstation (over
2500 workstations ) info quite regularly.

Hope this helps.
