When I do the same from the MacBook I get no related log entries at all.

could it be doing DNS-over-HTTPS?

For anyone facing a similar issue, I found the hint for my solution in this post: https://usercomp.com/news/1401699/sequoia-split-dns-lookup- on-macos

It appears to happen with MacOS Sequoia, if the DNS does not support EDNS0 packets. In this case the option "Limit IP address tracking" needs to be disabled for each network interface, which in my case was "on" by default.

Can the EDNS0 option be supported via dnsmasq?

The page at that link doesn't have much real information about what is actually going on. EDNS0 contains a whole set of options, some of which are supported by dnsmasq and some not.

I guess this is about the RFC-7871 client-subnet ENDNS0 option, but there's not really enough to go on in page to be sure what's happening.


Simon.



Thank you.
