DC RUM definitely supports monitoring IPv6. But there are several limitations.
Since there aren't a lot of customers monitoring IPv6 with DC RUM out in the field, our on-site gurus are unable to give you a solid answer I'm assuming.
Best to open a ticket with labs.
Sorry, that I created post as article, how I could convert it to "Ask a Question"?
I mean what if my DCRUM components (AMD, Reporting Server) will use IPv6 for internal communication? Does this case support by dynatrace configuration?
