Hello,

I have tested recently how Windows 11 behaves when resolving single label queries.

I have expected it might try to use LLMNR. But I did not expect it would do so also when trying nslookup, a tool which should be DNS only tool.

I have tried:

nslookup -type=ns com 9.9.9.9

Got NXDOMAIN. I were very suprised, learned that does not exist. Even more suprising were fact, that it presented the result came from the specified server. I am quite certain that server can resolve it successfully. When I run the same command on my Linux system, it works as it should.

nslookup -type=ns microsoft.com 9.9.9.9

Of course works as expected.

I would like to file some kind of bug. But have no idea how that could be done for Windows (desktop). Is there any bug tracker or at least documentation, why it does behave this way? Would you know a good contact to anyone from Microsoft, who may I contact? Is this behavior considered correct?

Thanks in advance!

Regards,
Petr
