When was the last time you could actually buy a tablet, laptop, desktop, cell phone that didn't support IPv6? You can get printers that support IPv6. You can get CPE devices that support IPv6. Games consoles support IPv6. Those that don't can be upgraded over the net. I'm not sure where TV's are at but the hardware supports IPv6 and just yesterday the TV asked my wife whether to download a new version of the software and this is a second hand TV. At $0 I wasn't going to worry if it supports IPv6. The dogs pulled the old one over smashing the LCD screen. Just had to find the right remote to press select. There is no reason the manufacturer couldn't ship a update that supports IPv6. Similarly for fridges. > Much > of it has to be replaced with newer h/w for v6 support or support folks > have to visit each site to perform upgrades (spendy).

If you have equipment that needs to be replace now it means you failed to plan. > How much quicker do folks think implementation would have been by vendors, > then adoption by users, had the ietf not felt obligated to rearchitect v4? > vs. just expand the address space and ship it, which is the only area where > v6 appears to shine anyway. [yes, I am ignoring the need for transition > mechanisms] I've got 15 year old equipment running IPv6. I've got lots of IPv6 equipment that has been end-of-lifed by the manufacturer. Windows XP supported IPv6 and that was releases in 2001. I've been running IPv6 at home for over a decade now. I was adding IPv6 to the products we ship ~16 years ago now and it has basically remained unchanged since then. If your consumer device does not support IPv6 don't blame the IETF. Blame the manufacturer. > I don't know anyone enchanted by v6. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@xxxxxxx
