| I am planning a move of our exchange servers and two domain controllers
out of our current single site to a new separate site. We had MS come in
and do a healthcheck on Exchange, and its one of their recommendations.
We don't have all the subnets in our network added into the current site
yet. Before I break out the netsh and AD cookbook scripts and go to the
lab I wanted to first see if there are simpler ways of doing this.
Question 1.
If I have say, 25 class C networks like 192.168.1.0/24 thru
192.168.25.0/24 in site 1. Can I put 192.168.0.0/16 under site 1 and it
work the same as explicitly defining the 25 separate subnets?
Question 2. The computers going to site 2 are part of a subnet in site 1
currently. Can I get away with adding individual computers to site 2
that are subset of a subnet defined in site 1?
Site 1 - 192.168.1.0/24
Site 2 - 192.168.1.10/32
192.168.1.11/32
192.168.1.12/32
192.168.1.13/32
Or do I need to move them into their own subnet for the separate site?
Thank you for any insight and/or recommendations you have.

Yes, however that includes more than just your 25 /24s. I'm sure your
network people have supernetted it in some fashion, because 25 /24s
isn't a supernet. 32 /24s starting at 192.168.0.0 is 192.168.0.0/19

Yes that will work fine

| Question 1: Yes, you can define one big one to replace the smaller ones,
but be aware that the bigger one is quite a bit bigger. In general, the
most specific subnet definition wins.
Question 2: Yes, you can even do individual IP addresses, but I'd avoid
it if possible because it quickly becomes an administrative nightmare.
I'd only do it for testing.

| 1. Yes this is fine and often recommended. Best to keep as few subnets as
possible just for the simplicity of it all and ongoing maintenance.
2. You could either carve out a little portion of the subnet for these
machines or move them to another "clean" IP segment or even just configure
the machines directly to use the specific site that you want them to use. If
you set the value of
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters\Sit
eName
to a specific site it will ignore the subnet/site topology for determining
the local machine's site. This can be messy/confusing especially if people
forget about it but I have found occasion to use it in a couple of
deployments where changing a machine's IP address was NOT an option but I
wanted the machines to be using a very specific set of GCs. Yes, the
application involved was Exchange. :)
