Hard to say. Too many variables to eliminate to figure out which software component is failing. If Windows is accessing the Internet correctly, presumably it's able to resolve DNS properly as well. It could be that Parallels is doing something "magical" as a proxy that the DNS Benchmark doesn't like. Start by checking if the DNS configuration inside windows makes sense for you.
Start by you bringing up a
CMD
window on the Windows 11 machine and entering
nslookup
. It should output something containing values you would recognize. It may help you recognize if it's your preferred DNS or if it looks like a proxy in Parallels.
Code:
Default Server: {some value}
Address: {some IP address}
You don't have a problem so it should work, but for kicks check by entering some host names, like
www.google.com
and see that you get a result back that makes sense. Enter
exit
when you're done.
