One day I really should do something about ipv6…

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.

What is there to tell? I’ve loved UNIX like things since I was first exposed to QNX in highschool (we had the Unisys ICONS!), and spent the better time of my teenage years trying to get my own UNIX… I should have bought Coherent in retrospect.. Anyways latched onto Linux in 1992, and then got some old BSD admin books and have been hooked on the VAX BSD & other big/ancient things since…!

  1. According to RFC2373, “A single interface may also be assigned multiple IPv6 addresses of any type (unicast, anycast, and multicast) or scope.” So even on a point-to-point link, you might have several addresses for each host.

    Of course, you might ask why you would want to do such a thing, but lots of people use virtual hosts on their web server; presumably some people might like to apply it to other protocols, like FTP or IRC.

    • sure I like having 100’s of addresses like anyone else (they still haven’t really fixed https in the client! it’s 2011!!!!) but for a router? All they need to do is barf out some OSPF/BGP table, and pass the flow……

  2. My ISP gives me an IP in /126 subnet for my public interface, and routes my /64 through that (and if I wanted, I could get a /56 instead – not that I have any need for it).
