[Netalyzr] DNS redirected to third-part​y servers: www.google​.com

[Nicholas Weaver]

I think this may be a false positive:

The systems respond like standard Google servers, both in normal communication and in errors (previous situations where this occured had the servers respond differently to errors than legitimate Google servers).  So it could be Google has added some new servers in Poland, but not updated the reverse DNS.  I will contact a friend at google to confirm...

However, if you want to be extra sure, you can switch to Google Public DNS (8.8.8.8 and 8.8.4.4
