Dear Mr.Mantas Mikulėnas, Mr.Lennart Poettering, and contributers for
systemd.
Thank you for your kindful reply !
Now, I am checking the detail behavior of resolved for my research by
taking your advices into consideration.
This is so helpful information to understand the resolved in details.
Sincerely yours.

Dear contributers for systemd-resolved:
Hello. I'm Ryota Matsufuji.
Could I ask a question about the behavior of systemd-resolved?
When being requested v4 and v6 address by application(such as wget with
default option or firefox),
depending on the interfaces' configuration, I watched multiple queries
for both v4 and v6 address are launched through those interfaces.
At this condition, I've found that systemd-resolved performed to return
the result of those queries to application
unless all queries are completed being resolved via one of multiple
interfaces.
I imagined that when A and AAAA record are received, disregarding any
interface completed resolving queries through itself,
resolved could return the result.
(for instance, received A from eth0 and AAAA from eth1, and not received
AAAA from eth0 and A from eth1)
Actually, It seems not as above.
If is there any reason or restriction that resolved should wait for
completing all queries through one of interfaces to return the result,
I'm afraid I would ask the question for why it is ?
I attached the pdf, illustrating the image of this behavior.
Furthermore, does systemd provide the configuration to switch this
behavior ?
If so, could I get the information about the config option?
Sincerely.
