dual-stack ipv4-IPV6 bug ? #462

Hello,
I notice a strange behaviour when browsing from a dual-stack ipv4 & ipv6 connection.
As I get IPv6 from openvpn tunnel, my ipv4 provider is different that my ipv6 provider.

My IPV4 ISp doesnt filter on RPKI. My IPV6 does.

The tool only reports my IPV6 ASN and name, but reports that it doesnt filter on RPKI. I suppose that the site is connecting to "invalid" URL using ipv4. Using ipv6, I have no route to "invalid" host, so filters work fine.

I would suggest to distinguish between ipv4 and ipv6, for the moment the result seems to be a mixture of the two?

Hello @jranma,
This has been mentioned in #37 (and to some extent #91).
Since this is more of an edge case, it was never implemented. Indicating the ISP on the connection that failed is probably doable but testing both protocols independently would require major changes.

ok, maybe explaining this in the FAQ ?
Personally I regret that all the developments are not thought in "ipv6 first", but this is my evangelist side... ;-)
