It's like everyone clammoring to bail out GM and save a bunch of low skill jobs that are going nowhere but overseas in the future anyway. It's a losing battle with the wrong objective.
Those greedy thousandaire GM auto workers are ruining this country. Millionaire bankers who created the great recession by purchasing bad mortgages and repackaging them with other bad mortgages via a formula not even the CEO's of their companies could comprehend, not a problem
... their mentally deficient counterparts at AIG who made millions selling insurance against those horrific bets ... not a problem ... those greedy thousandaire retirees from those evil socialist union loving auto companies ... clearly the problem here. Something must be done about these greedy thousandaires .... they are ruining this great country!!!!
Address shortages are a very, very, very tiny, miniscule fraction of IPv6. If IPv6 was about address shortages, the IPng working group would have adopted TUBA.
You seem unwilling to even recognize any of the other features of IPv6:
- Built-in security Built-in device mobility
- Built-in network mobility
- Built-in multimedia support
- Extensible headers for dynamic protocol upgrades
- Auto-configuration
- Reduced latency
- Improved router reliability (partly due to simpler routing protocols)
- Native multicasting
- Native anycasting
- Superior QoS support
Don't even think of coming back with "but nobody uses these" - nobody was driving until the car was adopted either. Things have a habit of not being used when they're not available. When they are available, they are used. It's as simple as that.
You've made some very important points however I would submit to you that when you look at the advancement of technology, specifically that which has widespread adoption, one clear pattern emerges. Better rarely beats more convenient. VHS versus Betamax, Laser Disc versus VHS, low quality MP3's versus CD's in the early days of Napster and the list goes on and on. IPv6 is superior in every way shape and form yet moving to IPv6 is a giant pain compared to keeping and in some way expanding on IPv4 and NAT in some fashion. Moving from IPv4 and NAT to IPv6 is a giant undertaking while continuing with IPv4 and NAT plus piecemeal advancement in technology as need arises is much easier. Remember that necessity is the mother of invention. I'm not saying it's the best path and I'm not saying widespread IPv6 won't be the eventual outcome, I'm simply saying due to the widespread adoption of IPv4 and NAT and the inconvenience of moving to IPv6 the trend will be to stick with IPv4 and NAT for as long as it's humanely possible and just when we get to the point when we think it's no longer possible there's a very good chance somebody somewhere will figure out a way to prolong it and as long as that road is easier and more convenient than moving to IPv6 then that's the road where history teaches us we'll eventually end up walking down
A budget is just a method of worrying before you spend money, as well as afterward.
