2.4 Other Considerations
2.4.1 License Key
In a DR scenario, the same license key that is used for Primary IPAM
Executive can be used for the DR Executive server also.
2.4.2 DNS Listener
If you run the DNS Listener on your IPAM production Executive, then you
will want to start the DNS Listener on the DR Executive upon failover.
Additionally, when configuring the master DNS servers which are
transferring updates to the DNS Listener, you should include the IP
addresses of both the Production Executive and the DR Executive in the
‘also-notify’ access match lists for the dynamic zones that are to be updated.
