Set your DNS server based on the SSID of your network
After MacOS removed the support to save dns servers based on your current profile, this repository contains somewhat of a fix for that. It listens to wifi changes and updates the dns accordingly.
This repo contains an installation script, just run it with ./install.sh.
Edit conf.txt with SSID:DNS pairs you want to set.
If your current WiFi doesn't fit with any given SSID, it uses the default set by your system (or DHCP).
