To setup your computer to work with *.dev domains, e.g. project.dev, awesome.dev and so on, without having to add to your hosts file each time.
- Homebrew
- Mountain Lion -> High Sierra
brew install dnsmasq
mkdir -pv $(brew --prefix)/etc/
echo 'address=/.dev/127.0.0.1' >> $(brew --prefix)/etc/dnsmasq.conf
echo 'port=53' >> $(brew --prefix)/etc/dnsmasq.conf
sudo brew services start dnsmasq
sudo mkdir -v /etc/resolver
sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/dev'
That's it! You can run scutil --dns to show all of your current resolvers, and you should see that all requests for a domain ending in .dev will go to the DNS server at 127.0.0.1
