That's a bit like comparing a German Shepherd and a Poodle to a Pig and a Giraffe. IPv4/IPv6 share the same architecture (same species) and base protocol, but use different addressing. IPv6 adds some sprinkles. They are inter operable to a large degree. NetBeui/NetBIOS and IPX/SPX were completely different animals. IPX/SPX had substantial benefits over NetBeui, specifically it could be routed and the broadcast overhead wasn't as servere. They shared no underpinnings (different species), and were not inter operable. You're making IPv6 out to be a much larger _core_ feature upgrade than it really is. > In terms of traction, here's a new data point for you: > > http://asert.arbornetworks.com/2009/09/who-put-the-ipv6-in-my-internet/ ROFL. Less than 1 percent (and from what God did Arbor get world wide network statistics?) You quoted an article using Hurricane Electric as it's crown jewel? HE is/was one of the largest spam hosts on the planet. Many mail admins/orgs block their entire IPv4 address space, including Nortel, a Canada based, worldwide telecom/network hardware manufacturer with ~25K employees. Makes you wonder why HE is pushing hard to transition to IPv6 eh? There was a very lengthy discussion about IPv6 on spam-l a while back. Unanimous opinion was that all inbound SMTP mail from IPv6 addresses would be outright blocked, period. Sending mail servers and MX hosts must stay on IPv4 addresses, period. The reason? Yep, you guessed it, spam. If everyone said, "sure, we'll accept your IPv6 mail traffic", overnight, spammers would switch to IPv6, making 15 years of antispam intelligence useless, and inboxen would overflow with thousands of spams/day again before the anti-spam crowd could catch up. The public internet mail stays on IPv4 kids, whether you like it or not. That's the way it's going to be, even if _everything else_ converts to IPv6, smtp mail won't. For the rather distant foreseeable future at least (10-20 years, maybe indefinitely). -- Stan
