IPv6 adoption hits 20%

About 2 years ago I noticed that IPv6 adoption was at about 7%. Well now IPv6 adoption is at 20% and still growing quickly. 20% is excellent! One in five people on the internet have an IPv6 address. This is the year of IPv6.

I'm still a little hopeful that this will mean that p2p technology will become viable again, but it's hard to say for sure. Security is much more important than it once was. I've also been burnt by the criminally cavalier approach to security that most companies seem to have. I may trust my router (barely) but not anything else. As a result I haven't turned on IPv6 on my router because I don't trust that everything on my LAN will actually do the right thing in that scenario.


Security on desktop and laptop machines isn't too bad anymore. The Windows 10 and OS X will ask the user if a program wants to open a port. Additionally, modern OSes do try and minimize their attack surfaces by not listening for connections when not required. I just can't remember if I've done something silly like turned on file sharing with guest access and that will be shared on the open internet. It wouldn't be the first time I've made that mistake. One of these days I'll have the time to experiment and see if file sharing restricts itself to LAN addresses. Also, if we get an public IPv6, does the OS also give us a private LAN address as well so we can bind more sensitive services only to that.
