Hi Guys,

We have two physical sites, with an Exchange 2010 Enterprise server in each. I have setup a DAG which is currently syncronising. However, I am confused as to the DAG IP. Which IP range should this IP come from, site one or site two?

See attached for my config.

what ip?

You must assign one or more IP addresses (either IPv4 or both IPv4 and IPv6) to the DAG. The IP addresses you assign must be on each subnet intended for the MAPI network and must be available for use. If you specify one or more IPv4 addresses and your system is configured to use IPv6, the task will also attempt to automatically assign the DAG one or more IPv6 addresses.

As an administrator, you can assign a static IP address for the DAG, though it is not a requirement. DAG doesn’t really care as long as it has an IP address and the name of the DAG is resolvable. The DAG name is not used by users or admins anyway. It is only used by the system for internal communication.

You can provide multiple IP address to DAG by following command.
If you have a DAG that spans multiple subnets (for high availability), you can configure multiple ip addresses for the DAG.

To find the current ip address of the DAG, run the command

Get-DatabaseAvailabilityGroup -identity "dagname" | fl *ip*

To configure multiple ip addresses, run

Set-DatabaseAvailabilityGroup -identity "dagname" -DatabaseAvailabilityGroupIpAddress 192.168.1.X, 192.168.2.X
