which ip scheme i have to prefer?

I have 1 gateway pc for all networks - 192.168.0.254
( that i can change any way)


now i want Hierarchy like -- 1 gateway
/ \
1 company 2 company
/ / / /
1 dept 2 dept 1 dept 2 dept
/ /
1 lab 2 lab

Now i want all network to be connected with same gateway.
and all networks can access each others pcs ( labs, dept, companies)

Plz. suggest me the ip range , which i have to prefer for the upper
diagram.

I also want that at any time i can chage ( disconnect) 2 different
labs , with the help of command line, (As physical disconnection of
cable is not preferable)


Suggest me some solution that i can implement for the network

Thanks

Regards

hi,
first if you want the ip range you have to provide some extra info like
-number of devices, how much will grow on next year or on future.

for disconnect an entire segment i will sugest you to work with VLAN - but
for that you need a switch with that option.

As Dragos said, it isn't simply a matter of IP addresses. How are you
going to set this up? What sort of hardware are you using ? Firewall,
switches, routers, VLANs?

ok, i will give you brief idea about my hardware and current network
settings.


I have 250 Machines , with 2 servers ( windows -2003 and Internet
sharer)


i have 15 labs each of 15 machines -- (15 * 15), staff will use
individual 25 machines

(Currently win-2003 server's ip : 192.168.0.1 , internet sharer
192.168.0.254, all lab machines are connected with 192.168.0.n and
192.168.1.n staff will use 192.168.3.n .....all having subnet mask
255.255.0.0 and gateway of 192.168.0.254 )

I have 10/100 switch connected over whole network.

Now i want that at any time, if i want to disconnect any lab from
other labs or server (win-2003) , it should be possible for me to do
the same without physical disconnection of cable or switch.

so i want to set such type of ip range that can solve my problem.

I want to implement it as fast as possible so guide me to do so.

Why do you think that it will be easy to isolate any group of machines?
You network is not segmented in any way. All of your machines are connected
to the same switch path and are running in the same IP subnet
(192.168.0.0/16). You just have one big single segment, single subnet LAN
with no isolation into groups.

Thanks for prompt reply.


Can i segment it out for different ip scheme? because my purpose is
only to differenciate out two labs when i need.


i m newbie to network and can't understand how to solve this?

Can u suggest me which ip and subnet i have to used?
Help me for the same

The simplest way to isolate the the two labs from the rest of the network
would be to put them in their own IP subnets and on their own switches and
put them behind a NAT router. The machines in a lab would be able to see the
Internet and other machines on your 102.168.0.0/16 network. But they would
not be able to see each other and the machines on your LAN would not be able
to see the machines in either lab. eg

Internet
|
gateway router
192.168.0.254
|
LAN machines
192.168.0.x/16 dg 192.168.0.254
| |
192.168.0.m/16 192.168.0.n/16
NAT NAT
192.168.21.1/24 192.168.22.1/24
| |
LAB1 LAB2
192.168.21.x/24 192.168.22.x/24
dg 192.168.21.1 dg 192.168.22.1
