Exchange 2016 Office Online Server External URL

In the process of implementing Exchange 2016. Have Mailbox and Edge Transport Servers installed and syncing. Was preparing to install & configure "OOS" and was unsure what URL's to use for Internal and External. It would seem they would be entirely different URL's from those proxies by the Edge Server into the Mailbox server, but point to the public IP of the Edge Transport Server. I wasn't finding anything explaining this. For example, for OSS, INTERNAL = OOS.internal.domain.org and EXTERNAL = OOS.domain.org (pointing to the Edge transport public IP). Not sure if this is correct or not.

 

If anyone might help me confirm my example assignments below I'd appreciate it!

 

FQDN                                      DNS Record Type          Value

domain.org                             MX                                 exch.domain.org (or mail.domain.org)

exch.domain.org                     A                                    External IP Address of Edge transport Server

owa.domain.org                     CNAME                           exch.domain.org

autodiscover.domain.org       CNAME                           exch.domain.org

oos.domain.org                      CNAME                           exch.domain.org

Open Windows PowerShell and run the following commands. When you run the commands, replace the example FQDNs and certificate friendly name with your own.
