The instructions are for Mac OSX via Homebrew:

brew install dnsmasq

dnsmasq is a lightweight dns server that will fallback to the original DNS server when it encounters an unknown domain

Add the line address=/www.your-domain.com/192.168.86.26 (my Mac ip in this sample) to the file /usr/local/etc/dnsmasq.conf

vi /usr/local/etc/dnsmasq.conf

The IP Address 192.168.86.26 is whatever the IP address assigned to your local computer by your router. You can find this via Network Utility (ifconfig)

sudo brew services restart dnsmasq

This starts dnsmasq process, and it will listen on the DNS ports

Edit your /etc/hosts

sudo vi /etc/hosts

127.0.0.1 yourdomain.com
