Why are some people here asserting that IPv6 failed when it looks like it is actually taking off pretty good right now? https://www.google.com/intl/en/ipv6/statistics.html Jan 2013 about 1% Jan 2014 about 2.5% Jan 2015 about 5% It is already past 9% so we will be at least at 10% by Jan 2016. Looks like a good exponential growth to me. The numbers for USA are even better at 21%. Traffic volume is also taking off: https://www.akamai.com/us/en/solutions/intelligent-platform/visualizing-akam... I will bet you good money that in a not too distant future we will see that IPv6 moves more bytes than IPv4. The IPv6 protocol is 17 years so it failed argument is meaningless. Maybe we needed IPv4 exhaustion before IPv6 could take off. No matter the reason, it is happening now. Regards, Baldur
