windows 2008 r2 server

I am using win 2008 r2 server.  I have setup a few printers and have manually added the ip address to them on the panel.  This is working fine but I wanted to know the correct way of going into the DHCP server and reserving this address.  Since I already assigned the address manual to the copier would I use a reservation in DHCP or would I use an exclusion range?

Use a reservation, you just need to know the MAC and TCPIP address of each of your printers.
You can exclude a range if you are going to use a block of addresses or you can do reservations.  The reservation would be preferable so that you know nobody changes the setting at the printer and gives it a different address.

Do I need to add the mac address in DHCP to the ip for the copier?
Yes, if you want for it to get an IP address.

If you're setting the addresses manually then the wise thing to do is to define a block of addresses for statically assigned network devices.  For example:

1 = Router
2-9 = Network Devices (Switches, etc)
10-19 = Servers
20-29 = Printers
30-250 = DHCP
NO Exclusion range.

If you want to set the printers to use DHCP, THEN assign a reservation.
How about this scenario.  I have a company that is going to install a cisco wireless router with 7 access points.  Then want 8 ip addresses they can use.  Do I do an exclusion range for this or do I do a reservation range or a reservation for each of the ip addresses I choose?
I would do a Reservation as well for that inline with What Lee W. states above.
If those are configured with static IP addresses, then you can do an exclusion.  But, logically decide a block to use for those exclusions.  I usually set those in the 240-249 range (or lower if I need more addresses).
Dumb question.  If I set the exclusion now before the routers and access points are installed will that work?
Yes.  That just means that the DHCP server will not be assigning addresses in that range.
Couldn't you just use an exclusion range for every network device that you want to have a static ip address for?  Why use a reservation?  Trying to learn.
A reservation guarantees a particular address is assigned to a particular device.

An exclusion range (even of 1) guarantees that address (range) is NEVER assigned by the DHCP server.  I don't see the point to exclusion ranges if you plan out your IPs before hand.  You'd simply define your contiguous scope and the addresses meant to be static would be from before or after the scope.
