I'm at the London Hilton Metropole for the 8th Groundhog day at the Name collision workshop: to see what question should be answered by research aimed at how the introduction of new gTLD strings may affect the the internal infrastructure naming system that exists in private network such as .home and .copr etc.
Geoff Huston tried to narrow the question further and talked about nifty ads-based imbedded solutions to measure DNSSEC, IPv6 etc from user's point of view and behaviour and possibly to be used for name collisions research aimed at root server analysis.
"When you delegate global name it changes the local area. This is the oppositte question. Is it the internal name of the search name result that collides with the search or something else?"
