Hello,<br>
<br>
I am on Debian Bookworm, SystemD 252.25 (bookworm-proposed-update).<br>
<br>
When I type ping <host> I have to wait at least 10 seconds to
have a response when the host resolves to an IPv6 address if dnssec
is set to yes, output when sending a ping to freedesktop.org:<br>
$ time ping -c1 freedesktop.org<br>
PING freedesktop.org(annarchy.freedesktop.org
(2610:10:20:722:a800:ff:feda:470f)) 56 data bytes<br>
64 bytes from annarchy.freedesktop.org
(2610:10:20:722:a800:ff:feda:470f): icmp_seq=1 ttl=44 time=143 ms<br>
<br>
--- freedesktop.org ping statistics ---<br>
1 packets transmitted, 1 received, 0% packet loss, time 0ms<br>
rtt min/avg/max/mdev = 143.376/143.376/143.376/0.000 ms<br>
<br>
real 0m22,106s<br>
user 0m0,002s<br>
sys 0m0,006s<br>
<br>
When disabling dnssec:<br>
$ time ping -c1 freedesktop.org<br>
<br>
PING freedesktop.org(annarchy.freedesktop.org
(2610:10:20:722:a800:ff:feda:470f)) 56 data bytes<br>

<br>
Still longer than sending a ping to a host resolving to an IPv4
address but really better.<br>
<br>
First of all, I thought it was because
<a class="moz-txt-link-freetext" href="https://github.com/systemd/systemd/pull/31827">https://github.com/systemd/systemd/pull/31827</a> was not merged to the
252-stable branch but it is since 252.24 according to the reply I
had when opening an issue.<br>
<br>
I cannot really test on most recent version of systemd, I prefer
avoiding breaking things so I don't know at all how it happens with
last version of SystemD.<br>
<br>
Are there some fixes pending on the 252-stable branch which could
potentially fix this still long delay?<br>
<br>
I am lost about how to obtain more diagnostics on systemd resolved
and where should I open an issue: on systemd-stable repository on
GitHub or on Debian?<br>
<br>
Best regards,<br>
