Isn't 003 Router the Gateway not the DHCP ip's

1. Isn't '003 Router' the Gateway not the DHCP internal ip nic?

2. Do you know of any issues if I use more of the scopes options?

3. Does 'reservations' prevent assumed scope options?

4. Shouldn't I set smtp, wins, www, etc.,. because each client would know a
assumed 8day scope on topology of network.

5.Wouldn't this prevent less traffic?

6. Does 'reservation' use lease cost route per scope option?

7. Couldn't each client have more than one nic wh each nic have different
reserved scope options?

8. If I setup using the above networking topology. Wouldn't this give the
most optimal and secured network as far as DHCP assigning the scopes? (this
doesn't include any other layered hdwr, services, srvs., etc.,.

Thank you in advance! Irwin

In the scope options form the DHCP server 003 is the Default gateway, the
ip address from the router in your network.
2. Do you know of any issues if I use more of the scopes options?

You can configure all options that are defined and that you really need.
Or what do you mean with the question?
3. Does 'reservations' prevent assumed scope options?

With a reservation you only "fix" an ipaddress to a MacAddress, the device
use the scope options from the scope where it is reserved.

You should only set the needed options, that's all. Lease time is based also
on your needs and what you like to set, with laptops where people often move
around you do not need 8 day leases, when they stay only one day in the company,
just fills up your leases and blocks other devices, if you maybe run out
of ip's on the scope. With only desktops that never move you can set a longer
lease time.

The release of the ip address is a straight forward task, will not slow down
the network.

What do you mean with this?

A workstation normally have only one NIC connected to a network, more is
not necessary and with different ip's one one workstation you can become
problems with routing or accessing data.

DHCP is always easy to configure, but to get control over connected machines,
it is more secure to use fixed ip's or use Vendor classes to only allow special
devices predefined in DHCP: http://technet2.microsoft.com/WindowsServer/en/library/13cbcfbd-2d9d-40fd-8b54-5c8090924eb21033.mspx

Additional you can also use manageble switches to allow only special MAC
addresses on the defined switch ports.
