If I use a VPN, who will resolve my DNS requests
Our VPN does not do IPv6 but my understanding is any IPv6 resolver will take precedent over IPv4 ones. Once we disabled IPv6 on the adapters then adjusted the metrics split-tunnel DNS resumed working. If your VPN supports IPv6 this is likely not needed and if the metric adjustment by itself fixes DNS for you keep IPv6 enabled on your adapter. If I use a VPN, who will resolve my DNS requests When a host has to do a DNS lookup, it does not know beforehand if the name it's looking up is in the VPN or not, so it cannot decide if it should use the VPN's DNS server or some other at that time. The closest you can get is to use a domain-specific override through dnsmasq (*nix), the built-in resolver (OSX), or something similar. – alzee Win 10: DNS resolution of remote network via VPN
