Introduction / Help

This is the IPv6 Web Resource Checker (webres6). It checks IPv6-only readiness of a Web page or app by crawling a given URL using Selenium and analyzes whether all page resources have been loaded via IPv6.

The IPv6-only Scores show the proportion of resources that could successfully be loaded via IPv6 only based on HTTP and DNS transactions.

Webres6 was inspired by Paul Marks' IPvFoo browser extension. While IPvFoo is more flexible and interactive, Webres6 can be run as a service and allows IPv6-only testing without installation or IPv6 on the users' client as well as automated analysis.

Further documentation can be found on the IPv6 Web Resource Checker project page on GitHub.

Limitations

The Selenium automation used is quite simple. It just loads the URL. As modern Web pages tend to be complex, this will most likely result in many resources not getting loaded/analyzed a normal browser would load.

The DNS checks performed by webres6 are a little fragile; They only check whether the hostname can be resolved from a recursive IPv6-only resolver. To get a complete picture, it is necessary to take a closer look at whole DNS delegation chain of all hosts involved for IPv6-only realness. You may want to try ready.chair6.net or running dig +trace from an IPv6-only host for that.
