Failure in test_network_connectivity_service.js

Not sure if it's limitation of android.
It might be WONTFIX.

Hi Valentin,

I have some questions about DNSv6 issue on android.

1. Could you explain a bit what exactly the issue is? I've tried to use about:networking#dnslookuptool to resolve example.org with fennec on android 9 and I do see ipv6 address.
2. In test_network_connectivity_service.js, why do we use localhost for ipv6 domain and why we use example.org for ipv4?

Thanks.

From what I can recall from writing the test the problem was that ip6-localhost didn't always resolve to ::1 on Android.
But from looking at /etc/hosts in both my Android phone and the emulator, that should work.
So maybe it's ok now? Give it a shot and see if it works :)

2. In test_network_connectivity_service.js, why do we use localhost for ipv6 domain and why we use example.org for ipv4?

Because hostnames defined in server-locations.txt normally resolve to a local IP - like example.com
But that doesn't seem to work for ipv6. So we used ::1 directly to check IP connectivity (not DNS).

Using ip6-localhost looks good on try.
