Route *.localhost traffic to localhost

Inspired and adjusted from this gist.

1. Install dnsmasq

brew install dnsmasq

2. Setup

mkdir -pv $(brew --prefix)/etc/
echo 'port=53' >> $(brew --prefix)/etc/dnsmasq.conf

# setup *.localhost
echo 'address=/.localhost/127.0.0.1' >> $(brew --prefix)/etc/dnsmasq.conf

3. Restart dnsmasq,

sudo brew services start dnsmasq

3. Add to resolvers

sudo mkdir -v /etc/resolver
sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/localhost'

4. Verify

scutil --dns

You should see a resolver like this:

resolver #9
  domain   : localhost
  nameserver[0] : 127.0.0.1
  flags    : Request A records, Request AAAA records
  reach    : 0x00030002 (Reachable,Local Address,Directly Reachable Address)
