Re: [afripv6-discuss] IPv6 rollout…

Dear Andrew,
Congratulations.
I look forward more details to share with my universities.
Best Regards.

universities turned up IPv6, in a fairly consistent manner.  Now, I'm not
talking about turning up IPv6 on a few servers, I'm talking about
integrating it into every part of their network.  By 2:30am this morning it
was running on all their proxy servers, all their residence networks, the
wireless networks, all the lab PC's and a good portion of the staff
network.  The topology used was identical to that of the IPv4, and as the
rest of the network is migrated to the new IPv4 topology V6 will be
implemented on everything in dual stack along side that as well.

 So flawlessly infact that even with Apple's default implementation of
Happy Eyeballs that tests RTT and defaults to v4 if the v6 latency is
higher, the apples we tested on running lion and mountain lion were still
choosing ipv6 most of the time.

rearchitecture the entire network (that had to happen anyway for various
reasons), and we added the v6 as part of that project.  It would not have
been possible to do that without first getting our hands on another /15
worth of IPv4 space though to allow that rearchitecturing to happen
properly.

more detail and send through some graphs and other information, I just had
to share the fact that we're seeing at points half the traffic on a
standard university coming in from the internet over ipv6!
