if you know anyone who is filtering /48 , you can start telling them to STOP doing so as a good citizen of internet6.
I had a bit of off-list discussion about this topic, and I was not going to bring it up today on-list, but since the other point of view is already there, I may as well.
Unless you are going to pay the bill for my clients to upgrade their 3BXL/3CXL systems (and similar) to XXL and then XXXL, I think we need to do two things before IPv6 up-take is really broad:
1) absolutely must drop /48 de-aggregates from ISP blocks 2) absolutely must make RIR policy so orgs can get /48s for anycasting, and whatever other purposes
If we fail to adjust RIR policy to account for the huge amount of accidental de-aggregation that can (and will) happen with IPv6, we will eventually have to do #1 anyway, but a bunch of networks will have to renumber in order take advantage of #2 down the road.
Hi Jeff, We could use smarter prefix filtering than that. Which was proposed to ARIN a couple years ago. And failed. http://lists.arin.net/pipermail/arin-ppml/2009-November/015521.html Regards, Bill Herrin -- William D.
