So, you can take ARIN fees off of my list. The rest still stands.
OK, so let's go back to the original list: L3 routing/firewalling upgrades required, specifically mentioned was 6509 and 7206VXR. Someone else commented that the 7206VXRs were CEF switching IPv6, and I can confirm that the 6509's L3 switch IPv6 in hardware as well. The only caveat is finding the right firmware that has it with the mix of line cards that you have in your chassis. Overall, however, the platform does support it. Obviously Cisco has a *huge* product line, and I doubt we'll ever get a full accounting of what does and doesn't do IPv6 "in hardware" on this list, but to claim that you have to replace all of your hardware, is certainly a large exaggeration. ISP support Most of the major Internet backbone providers offer IPv6 support of some sort, admittedly not all do, but most do. Ask your providers and there's a good chance they can deliver it to you. Yes, some are still doing tunnels for it, but they do work well. Besides, you're presenting a false dichotomy, if you go digging, there's a decent chance that your IPv4 traffic is also using a tunneling technology within your providers' networks as well, frequently MPLS. Tunneling IPv6 in IPv4 is not fundamentally different. ARIN support This one has already been covered. SBC support This was part of the whole point of the thread. Why hasn't the voice industry adopted IPv6 more aggressively? I was including the SBC (and other gear and software) vendors in the voice industry there. Yes, this is probably the only real obstacle you presented that would prevent voice operators (admittedly the focus of this list) from really deploying IPv6 aggressively, but I will say that my commentary was commentary about the overall industry, including the gear and software vendors. Seriously, IPv6 makes so many things work so much easier...just in eliminating NAT, particularly for SIP...that, yeah, I think its a no-brainer to be working towards this. Maybe its not feasible to get it running in a production level today, but if you've got vendors roadblocking you from getting there, they should be hearing from you that its just not acceptable. The payoff (particularly for VoIP protocols) is just too great. -- Jeff McAdams jeffm at iglou.com
