brew install dnsmasq

# start service
sudo brew services start dnsmasq

# config computer to resolve with dnsmasq
sudo mkdir /etc/resolver
sudo sh -c 'echo "nameserver 127.0.0.1" > /etc/resolver/localhost'

# refresh resolvers
sudo dscacheutil -flushcache  
sudo killall -HUP mDNSResponder

# check it's working
