RE: [ActiveDir] another dhcp question

I don't see any reason.

 

Unlimited is a bad idea because you'll ultimately run out of addresses unless you do manual housekeeping.  There's a similar issue with reservations, but because you're making the reservations manually, you're more likely to keep an eye on hosts you remove from service.

I assume you should give DC's a static address and not use reservations or does it matter?

 

Also, if you set the reservation for unlimited, do clients still periodically check with DHCP to see if their addy is still valid?

If yes, is this a good thing or does it create some latency and unneeded traffic that you would be better off remaining static?

 

Thanks

The DHCP server obviously requires a static address, but you can still enter a reservation for it so you see it in the table.

Just so I am clear on this: you reserve the addresses and set the servers to use DHCP. What about the DHCP server itself? What if that is running on a DC?

A big pro is that if you change your DNS or WINS servers' IP addresses, router address, or domain name, you don't have to visit every system to make the change.  You can just plan ahead, reduce the lease renewal period, and then update the property in one location.

What are the pros and cons of using reservation with unlimited lease instead of static addresses for servers and network printers?

 

Thanks a lot.
