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. The way we are headed right now, it is likely that the IPv6 address space being issued today will look like "the swamp" in a few short years, and we will regret repeating this obvious mistake. We had this discussion on the list exactly a year ago. At that time, the average IPv6 origin ASN was announcing 1.43 routes. That figure today is 1.57 routes per origin ASN. -- Jeff S Wheeler <jsw@inconcepts.biz> Sr Network Operator / Innovative Network Concepts
