[arin-ppml] IPv6 Non-connected networks

[cja@daydream.com]

Michael,

Sure I can give you an example.  At one point the company I worked for
received 24.0.0.0/14.  It was not globally routable.  For some time, I would
say close to a year, Sprint would only listen to advertisements for
24.0.0.0/8.  Everyone who had a block of net 24 would advertise that block
as well as 24.0.0.0/8 and depending on the day and how lucky you were if
Sprint preferred your advertisement to 24.0.0.0/8 then you could get to
Sprint customers.  The other issue regarding this block was that most of the
world didn't have their routers configured to understand a subnet of a
traditional "class A" block.  So our NOC spent probably 1/2 it's time
tracking down these sites and getting them to add the appropriate commands.


It was a ton of fun!
