$ ./show-ipv6-usage-per-ISP-for-TLD.sh NL

Dutch cable ISP Ziggo starts IPv6

Good news: Ducth cable ISP "Ziggo" has started the rollout of IPv6. See article (in Dutch) on http://tweakers.net/nieuws/102311/ziggo-begint-met-uitrol-van-ipv6.html

Ziggo spokesperson Gradus Vos confirms the rollout has started last week (around beginning of April 2015), and so far 6.000 users have been assigned IPv6 connectivity.




Netflix and "This webpage has a redirect loop"

Suddenly Netflix was not working anymore: my Chrome on Ubuntu Linux said "This webpage has a redirect loop" on www.netflix.com.

Netflix advised to clear my cookies.

The real cause was different: IPv6, and possibly my Hurricane Electric IPv6 tunnel.

After disabling IPv6 in Chrome with the startup command "google-chrome --disable-ipv6", Netflix was working again.

Great. Not.

EDIT: I found a dirty workaround: I put this into my /etc/hosts

54.197.238.114 www1.netflix.com

... and now a plain google-chrome startup (so with IPv6 enabled) leads to a working Netflix!

EDIT 2:

Thijs Kroesbergen (@TheIceCoMa) reports a Netflix problem with Sixxs IPv6:

https://twitter.com/TheIceCoMan/status/585829217046294528

@NetflixNL IPV6 on the http://netflix.com  site is broken (connection timeout on the first HTTPS request) coming from a SiXXS tunnel.

EDIT 3:

Windows 7 & Chrome on the same LAN (so: with tunneled IPv6) correctly works with Netflix. Strange
Ubuntu & Netflix with Pipelight works too with Netflix
