Thanks for this.

I would expect that the key things to prove are the statements in the draft. Also, any observations that might come up would be useful. For example, was it fair to say that the network that was isolated remained isolated? Did using a ULA and a GUA on a globally-accessible network cause any issues? What, if anything, was necessary in the router(s) in question to prevent hosts from using ULA source addresses to connect to GUA addresses? Did hosts in fact form both ULA and GUA-based addresses and use them appropriately when connecting to applications inside and outside the network? 

What one might hope would be that ULA-based addresses were used to connect to other ULA-based addresses, as their bit strings were most similar, and GUA-based addresses were used to connect to other GUA-based addresses, for the same reason. One might hope that ULA prefixes were not announced in BGP without needing extra thought, and that if they were announced, they were not accepted. One might further hope that when a ULA was not announced into a neighboring domain, a packet sent to the ULA prefix didn’t cross the domain boundary.

Of course, we need to hear about any extra work that was required, and any problems that arose. And we need to understand if the deployment of a ULA prefix necessarily implied the deployment of an IPv6/IPv6 NAT or NAPT. I don’t expect that it will and am certainly not asking for it to, but that expectation has been promoted.

JANOG will be Wednesday-Friday the week before IETF 90, and v6ops will meet Monday and Tuesday. It would be nice if someone could make a point of reporting on the experiment.
