Hardly anyone support IPv6 these days. Sony KDL40*X70* internet-enabled LED-LCD-TV, 2010, IPv4-only (bought 7/2010) Western Digital MyBookWorld2 HomeNAS, 2009, IPv4-only Nintendo WII appears to be IPv4-only > 95% of all home-DSL-Routers in Germany IP (100% from the folks I know) are IPv4 only. most home users in Germany can not even get IPv6 from their ISP, even when they had an IPv6-capable DSL-router. What capabilities there are available on the internet backbone or what could be enabled on newer operating systems by sophisticated end users doesn't matter much, if most of the "internet-enabled" end user equipment, that is being sold to consumers, is still IPv4-only. What we desperately need is factory-enabled transparent internetworking on all _NEW_ networking equipment and internet-enabled gadgets and appliances. As long as IPv4 and IPv6 are seperate worlds the hen-and-egg stalemate is going to continue. And the useful lifetime of all brand-new IPv4-only equipment that is produced by the electronic entertainment industry is about 5-15 years. -Martin _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
