--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
The pcap file indicates that two A queries are sent, and no AAAA query. The
queries are sent in parallel, with different source ports. This is rather odd.
With the glibc stub resolver, there should be an A query and an AAAA query,
from the same source port.
Is a VM involved somewhere? Did you capture the packets in the VM or outside
of it?
