But in IPv6, due to ping-pong and just so many technical manuals and other advices, you are told to "just use a /64' for your point to points.
Isn't it a /127 nowadays, per RFC 6547 and RFC 6164? I guess the exception would be if a router does not support it.
Best practice used most places is to assign a /64 and put a /127 on the interfaces.
Thanks for the info. Is this documented somewhere? Is there a disadvantage in letting many P2P links use different /127 networks within the same /64?
Primarily human factors. Owen
