DHCP & Subnets

Ok So I am trying to learn how to subnet with Windows Server 2003
DHCP.

This is what Ive done using a random Class C network...

Set up a new SuperScope in DHCP server which contains 5 Subnet'ed
scopes

199.31.0.0
199.31.64.0
199.31.128.0
199.31.192.0
199.32.0.0

All systems on my network are running Windows XP and are already
configured for DHCP.

I have about 10 systems on this network. All are running Windows XP
and DHCP. I know that this subnet is way more than I need, but I am
just using these numbers as an example. I have
4 PCs in one room connected to 'Switch A' and 5 in another room
connected to 'Switch B' and both switches are connected to a router.
The Win 2k3 server is connected to the router as well.

My question is how do I direct a particular system to a specific
subnet? Like I said, i am just learning so if you can direct me to a
website that gives details that would be great too.

thanks

You don't
You don't subnet with DHCP
You don't use Superscopes for normal subnetting,...you use Superscopes for
Multi-Netting.
Multi-Netting makes multiple IP Segments behaves as a single segment and
operate over the same wire. So it doesn't matter which IP Segment the
machine is part of. The Superscope can give an address from any one of the
packeged scopes at any point in time, that is the whole point of using a
Superscope.
You can not do any subnetting of any kind without a LAN Router

If you are "learning subnetting" then stay away from Multi-nets &
Superscopes. I've been doing this for years and still refuse to even touch
something like that. VLANs have pretty much eliminated the need for
Multi-Nets and Superscopes anyway.

Ok thanks..

So then what do I do to assign specific subnets to these machines?

Start out by not using DHCP and statically assigning the machine. You don't
"assign" subnets,..you just give the TCP/IP config they are supposed to have
and that is it. The subnet is automatically determined by the IP# and Mask
combination.

Each subnet needs to be on a "wire" of its own the a LAN Router needs to
sits between he individual "wires".

I have two different nets connected via a 6509 Cisco switch with router
module. If you want to put certain areas on one segment and others on
another you will have to use Vlans basically. By assigning what traffic is
allowed through which port you can delegate which net pool that dhcp is
tossing out a lease from. Understand?

Our company reserv 3 floor in our building. each floor with a siwth, each
floor have cat6 connec to computer room. But now the PC grown, IP not
enough. So I need create new IP subnet. My idea as below. But i don't is
work or not.

Server Room = Cisco 2950 24 --- two wire connected ( subnet a ,
DHCP )------> Router 1721 with two 4 port interface -----> two port connect
to 1 floor switch hub (subnet1)-------> two connect to 2 Floor switch
hub.(subnet 2)

That mean the 1721 router for gateway connect to different subnet
My question as below.
- how to setup differnet in Subnet a DHCP server
- I need each subnet can be access Server room pc.
- how to defind to cisco router commend.

Please advice.

Thanks
