Hi all.
While reading up on IPv6, I've seen numerous places that subnets are now all /64.
I have even read that subnets defined as /127 are considered harmful.
However while implementing IPv6 in our network, I've encountered several of our peering partners using /127 or /126 for point-to-point links.
What is the Best Current Practice for this - if there is any?
Would you recommend me to use /64, /126 or /127?
What are the pros and cons?
