Yes,you can create different AD sites location wise/deptwise,etc and map the subnet to appropiate site.

10.10.10.0/24 would only indicate the addresses from 1-254
10.10.10.0/23 would indicate 512 addresses from 10.1-11.254
10.10.10.0/22 would indicate 1028 addresses from 10.1-13.254

You pick wich subnet and assign it to the default site if you only have one.

what is the first and last  IP address on 10.10.10.0/22 ?

Ok I see it here:
http://www.aboutmyip.com/AboutMyXApp/SubnetCalculator.jsp?ipAddress=10.10.10.0&cidr=22

the number 8 makes sense to me but not the 11 on the 3rd octet

First host: 	10.10.8.1 	00001010.00001010.00001000.00000001
Last host: 	10.10.11.254 	00001010.00001010.00001011.11111110

Select allOpen in new window

The clients in the domain will be in 10.x.x.x and 192.x.x.x subnets

it is going to be one AD site.
So do I need to associate the subnets with that one site ? if so the How?

I will open a new question for the subnetting later

In the case if I need just one AD site, but using the 10 and 192 networks.

would that one site figure it out automatically, or I still need to add the networks(10 and 192) to the site.

Jailhunt.

if I want to use 10.10.10.0/22 for instance , then I can just create or use the default first site name, create a subnet 10.10.10.0/22 and associate the site to the subnet.

but if I have 10.10.10.0/22 and 192.168.1.0/23, how can I associate the default first site to both 10.10.0/22 and 192.168.1.0/23 ?
would AD Sites and Services allow you to associate both the networks(10 and 192) mentioned above to the default first site at  same time?

thanks

I want to make sure that there will be no problem associating to different subnets such as:
10.10.10/22 and 192.168.1.0/23
to the same site  DAL

thanks
