[Dnsmasq-discuss] trouble with conflicting DNS resolution on MacOS

Thu Jan 9 21:22:45 UTC 2025

Hi,

I am having suddenly troubles with resolving DNS entries on macOS 
Sequoia 15.2.
I do not think this is related to my dnsmasq configuration, but maybe 
someone discovered something similar and might be able to help.

I have a local network with the domain "prager.homeip.net" and local a 
host "odin".

'dig' resolves the local host correctly, but 'ping' tries to connect to 
the external network ip address instead.

Would anybody have an idea what could be wrong and how I fix this?

Thank you,
-- Bernd
