Kevin, thanks for your comment. I have no professional background in IT, so I really appreciate your remarks. > The most valid use is when you can only get a /64 from your provider. I got a /112 for each of my virtual servers... So, I decided to go for ULAs for the VPN between them. > I really guess all of this needs to be in the handbook so people don't > waste time trying to do things that are documented to either not work > or not work effectively.

I guess I could have known, if I had read the RFCs, but adding some notes in the handbook(s) would ease things a lot.
