[chromium-discuss] DNS_PROBE_FINISHED_NXDOMAIN & Dual stack

[Ciro Iriarte]

Hi,

I'm having a weird experience with name resolution, the client is running
dual stack (IPv4+IPv6). Having received two DNS servers, one on each
network, the OS can resolve without issues:

roamer:/etc/zypp/repos.d # cat /etc/resolv.conf
nameserver 192.168.43.1
nameserver 2800:c70:c6:18::d9

roamer:~ # dig +short @2800:c70:c6:18::d9 www.google.com A
216.58.192.36

roamer:~ # dig +short @2800:c70:c6:18::d9 www.google.com AAAA
2607:f8b0:4008:80e::2004

roamer:~ # dig +short @192.168.43.1 www.google.com A
172.217.1.100

roamer:~ # dig +short @192.168.43.1 www.google.com AAAA
2607:f8b0:4008:805::2004

But Chrome cannot resolve IPv4 only sites, giving DNS_PROBE_FINISHED_NXDOMAIN
in those cases (www.suse.com, www.twitter.com). Sites with IPv6 load
without issue (www.gmail.com).

Tried with Firefox, and it's working as intended for any valid destination.

OS: openSUSE Leap 15.0
App: google-chrome-stable-70.0.3538.67-1.x86_64

Any ideas?
