But the one thing that did drive me nuts was using /64’s everywhere… even p2p (that’s point to point!) links where even a 3rd host is impossible. I mean it is incredible to have 18,446,744,073,709,551,616 (2^64) addresses per network, but to use 2 out of the 18,446,744,073,709,551,616 just seems insane!!!
Luckily I’m not the only one that shares this opinion, Jeff Doyle does as well.
Long story short: Give up your ipv4 mentality, and just get used to it. ARIN is pushing people to /64 things like T1/E1/J1 connections.
