[v6ops] IPv6 ready Web pages (Was: Re: Halfway there?)

[Philipp Tiesel <[e-mail]>]

Hi,

It’s actually pretty hard to say whether a web page is really IPv6 ready.
There is a lot involved including DNS and probably resources accumulated over several levels of dependencies.

I built a tool for that – https://webres6.dev.sap/
- It tries to fetch a page with all resources
- It tries to analyze DNS dependencies
- It squeezes everything into a percent score…

Happy to get feedback on it.

Known Issue: Some CDNs might interact badly with the “give-up” logic of libunbound I use for DNS tests.

AVE!
   Philipp
