The bug has nothing to do with whether IPV6 traffic is generated or not.

If you have ipv6 enabled, GLIBC will try AAAA DNS requests, and the
behavior of how this is done in conjunction with normal A record
DNS requests is what causes problems with some equipment.

But these DNS queries happen over ipv4 in your configuration.
So if you want to "see it happen" you need to trace ipv4 traffic,
looking for DNS queries.
