Re: V6 still not supported

[JORDI PALET MARTINEZ via NANOG <nanog () nanog org>]

My guess is that fixing that means fixing tons of games/apps. They are somehow presuming that every user of the game 
has a different IP.

Note that we are talking only about PSN because it is probably the most affected one, but I heard about other services 
with similar problems and similar blockings.

I'm convinced that it will be cheaper and much easier to port to IPv6 those games/apps and at the same time be a 
long-term solution.

    My apologies for expressing myself poorly.

    What I meant to say is that this is primarily a problem caused by Sony and the Sonys of the world. Less so a 
problem inherent to IPv4. A root cause fix would address Sony's hostile behavior.

    No, isn't only a Sony problem, becomes a problem for every ISP that has customers using Sony PSN and have CGN 
(NAT444), their IP blocks are black-listed when they are detected as used CGN. This blocking is "forever" (I'm not 
aware of anyone that has been able to convince PSN to unblock them). Then the ISP will rotate the addresses that are in 
the CGN (which means some work renumbering other parts of the network).

    You do this with all your IPv4 blocks, and at some point, you don't have any "not black-listed" block. Then you 
need to transfer more addresses.

    So realistically, in many cases, for residential ISPs it makes a lot of sense to analyze if you have a relevant 
number of customers using PSN and make your numbers about if it makes sense or not to buy CGN vs transfer IPv4 
addresses vs the real long term solution, which is IPv6 even if you need to invest in replacing the customer CPEs.

        Not to necessarily disagree with you, but that is more of a Sony problem than an IPv4 problem.

        It is not a fixed one-time cost ... because if your users are gamers behind PSP, Sony is blocking IPv4 ranges 
behind CGN. So, you keep rotating your addresses until all then are blocked, then you need to transfer more IPv4 
addresses ...

        So under this perspective, in many cases it makes more sense to NOT invest in CGN, and use that money to 
transfer up-front more IPv4 addresses at once, you will get a better price than if you transfer them every few months.

              IPv4 address blocks have a fixed one-time cost, not an ongoing $X/month cost.
