So + 8% in four months time, or + 2% per month. Well done, KPN!
That could mean KPN could be at 14% + 12*2% = 38% IPv6 traffic at the end of 2017. We'll see in one year time.

Interesting: IPv6 traffic is the majority of my Internet traffic at home: 54%. And IPv4 is the minority.
Calculation (thanks to the MRTG monitoring of my router):
IPv6 traffic has an average of 366.0 kb/s
Total IPv4+IPv6 traffic has an average of 676.4 kb/s
So divide those numbers IPv6 by total traffic: 366/676 = 54% IPv6 traffic.

Zo, mooie score van KPN: op 4,65% IPv6 deployment (meting september 2015). En "deployment" betekent hier daadwerkelijk gebruik, dus tot op computer/tablet die het daadwerkelijk gebruikt.
KPN had in april 2015 (5 maanden geleden) nog geen IPv6 deployment (tenminste: blijkbaar minder dan 0.00%). Zie http://ipv6-or-no-ipv6.blogspot.nl/2015/04/ipv6-deployment-by-isps-in-netherlands.html
