The Austin Active Directory resides on multiple networks on campus and in the cloud and these networks are detailed in the tables below. The Austin Active Directory also contains subnet objects for associating devices to the nearest domain controller. See Active Directory Sites and Subnets for information on Active Directory Sites and Active Directory Subnet objects
The IP subnets listed in tables below are the supported values for defining the Austin Active Directory networks in firewall rules and other solutions that restrict network traffic based upon IP addresses.
The use of individual IP addresses instead of IP subnets is not supported by the Active Directory team as components of the Austin Active Directory may change IP addresses within the defined subnets as needed.
