DHCP Question

win2k8

Hello All,

I started studying for my 291 exam again. And i was watching the cbt nuggets section on DHCP. And I had a question, when your running out of IP addresses, he talks about a "super-scope" and all he did was create another scope and then right click on the server and added the original scope to the second scope. But, my question is a super-scope really necessarily? Can you not just have two separate scopes on different network segments and still increase the number of IP addresses?

Thanks,

Hello Mate,

I understand you are just beginning your 291, once you finish your DHCP chapters you will actually understand the difference.

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.
