Can you have a smaller subnet in a larger subnet in AD Sites and Services?
Posted on 2011-09-19
Currently we have a subnet defined in Windows 2003 Sites and Services as 10.64.0.0/13. What we have been asked to do is assign a different site code to a range defined as 10.65.238.217/29. What I would like to know is whether it is feasible to aasign a smaller subnet of addresses a different site than what has already been defined to the larger subnet? We know that we can make a individual IP address a different site by placing the IP address in Sites and Services with a 32-bit mask but we've only done this on Domain controlller's where we've wanted to isolate the DC for disaster recovery purposes. For a 29-bit mask I can certainly add 6 individual IP addresses in Sites and Services to cover their testing but if the test is successful they'll want to carve 1/2 of a class C address space out of the large space and if I can define a smaller space inside the large it would make my life easier,
