Is there anyway to automate the reservation process in DHCP?

Hey,
Right now I manually handle the reservations for the hostnames in DHCP. I
was wonderign if there was a way to automate this process. Meaning as soon
as a lease is assigned it is automatically reserved by default.

Thanks.

No, not that I know of. Maybe some scripting guru could do it for you (try
posting in a scripting group), but my question is, why do you need
reservations by default? What's the point? I use reservations for printers,
etc., and the few desktops I support that for some reason require
non-changing addresses, but that's it.

Note that DHCP reservations do not provide you with security - so if you're
trying to prevent unauthorized laptops/etc from connecting to your network,
this ain't going to do much for you.

Reservations offer more than a fixed IP address.

They can be made in address ranges excluded from the DHCP scope - this
allows for 2 DHCP servers in x.y.z.0 subnet with over 127 hosts.

Each reservation can have a specific Remote Gateway assigned, different from
the Scope Option. This allows use of multiple ADSL lines which are much
cheaper than a dedicated 100Mbaud broadband link here in the UK.

Thanks for all the replies.
The main reason for the reservation is that the Windows DDNS has to
interface with a larger static DNS system and changes in the DDNS system have
to be reflected there.
So I'd rather just do this once. Posted in the scritping forum.

Ah. Thanks, Newell....I've never needed any of those settings so I hadn't
thought of that.
