Introduction

Sometimes you may want to use a DNS server for specific domain requests and another DNS server for all other requests. This is helpful, for instance, when connected to a VPN. For hosts behind that VPN you want to use the VPN's DNS server but all other hosts you want to use Google's public DNS. This is called "DNS splitting."

Here, we run dnsmasq as a background service on macOS. The dnsmasq configuration described below implements DNS splitting.

Install

brew install dnsmasq
