Hello,

My apologies for this post in English, unfortunately, my German is not fluent yet.

I have an issue that is very close to https://telekomhilft.telekom.de/t5/Telefonie-Internet/DNS-Adresse-MacbookAir-an-Speedport-S3/td-p/5207954 . When I use Macbook Pro ( OS Monterey v12.4)  I cannot do web surfing due to DNS resolving issues. Ping command to any IP address is always successful, however, nslookup fails with the following error:

nslookup cnn.com

/AppleInternal/Library/BuildRoots/b6051351-c030-11ec-96e9-3e7866fcf3a1/Library/Caches/com.apple.xbs/Sources/bind9/bind9/lib/isc/unix/socket.c:2132: internal_send: fe80::1%6#53: Network is down

;; connection timed out; no servers could be reached

My DNS settings by default configured in the following way:

If I remove IPv6 DNS server address and provide only 192.168.2.1 everything works fine, the problem is only that WLAN configuration in macOS is not network specific, and if I connect to any other WLAN outside the home, I need to change the settings to default.

My suspicion is that browser or OS tries to use IPv6 DNS server address to resolve DNS name which fails and after that tries to use IPv4  address which is usually successful. 

An interesting point is that I have issues only with macOS, other devices at home work fine.

I am wondering who has faced the same issue with macOS? Any workaround?

Thanks!
