Hi

Just a simple question:

I have a DHCP server e.g. D

and an existing superscope say S

now, i want to create a new scope

THE QUESTION IS: are there any difference (in function) either i create
the scope under the server D or under the superscope S?

Looking for any comment.

Thanks in advance

(Unless they have change the GUI) you cannot create a
scope "under a superscope" -- you create and add it to
the superscope.

If you understand the purpose of a superscope explicitly
it will make it clear when to use Superscopes.

First, a mental trick: Every time you hear the word superscope,
mentally (out loud at first) add the word "GROUP" so it becomes
"superscopeGROUP" - scopeGroup would have been a much
better name for this but that's not what the RFCs chose.

A superscope(group) is used when you have a MULTINET--
more than one 'logical subnet' on the same 'physical subnet or
segment of wire'.

You want the DHCP server to service both subnets -- a scope
is related to ONE Subnet.

So create each scope (per logical subnet) and create a superscopeGROUP
because you have a multinet -- add the scopes to the superscope...to
group them.

It's just a scopegroup.

Why not? In win2K, right click the dhcp superscope and create a scope,
it will automatically under that subscope, of coz you can manually add
them later.

Then they have changed the GUI (as I noted might
be possible) but the key is how or when to use the
Superscope, not whether you add the scopes or
create them "under".

IF you need a superscope, you must (end up) place
the scopes under it.
