[AusNOG] Stupid web browser behaviour Was: My Predictions for the ISP Industry

[Craig Askings]

Hi Geoff,

Are you noticing a difference in ipv6 preference when dual stacked 
depending on which web browser being used? Can you even detect browsers 
that have just decided to stop using ipv6 even though it is available?

<rant>

For example on my dual stack connection at home when I go to 
(http://labs.apnic.net/measureipv6/) it works first time with Firefox 
but fails with Chrome because it has yet again decided to stop asking 
for AAAA records.

For those playing along at home go to chrome://net-internals/#dns in 
chrome and see what it has decided to use as it's "Default address family"

</rant>

However my suspicion is that this industry is definitely not sentimental - as soon as interest and more importantly the money wanes the technology rapidly disappears!

If you run a web site, you can help us to measure the IPv6 capability of your client base, even if your site is IPv4-only today. Details of the IPv6 measurement program are at http://labs.apnic.net/measureipv6/, and if you want to help us  and inform yourself about the IPv6 capabilities of folk who use your web site, a way to do this is at http://labs.apnic.net/tracker.shtml
