+===== Smart Multi-Homed Name Resolution =====
+From [[https://www.qwealthreport.com/windows-10-users-beware-of-this-new-security-risk/|here]].
+Under Windows 7 all DNS requests were made in simple order of DNS server preference, but this changed in Windows 8 when Microsoft added “‘Smart Multi-Homed Name Resolution” by default. This sent out DNS requests to all available interfaces, but only used non-preferred servers if the main DNS server failed to respond.
+This makes Windows 8.x systems liable to DNS leaks, but at least makes it unlikely that DNS requests will be hijacked.
+Windows 10, on the other hand, simply chooses whichever DNS request responds quickest, which presents a major security risk.

+Windows 8 and 8.1 could use registry to disable SMNR. Windows 10 needs Group Policy set (not registry)
