Setting dnsmasq for wildcard domains in ubuntu

This is useful for development environments like vagrant and docker, where you can play with FQDN instead of IP:

# edit according to your needs
DOMAIN=dev
IP=10.0.10.100

# append to configuration file
sudo echo "address=/$DOMAIN/$IP" > /etc/NetworkManager/dnsmasq.d/dev.conf

# restart network manager
sudo stop network-manager
sudo start network-manager

The above will resolve the *.dev domain on IP 10.0.10.100.

Note that this is the version bundled with network manager and not the dnsmasq package.
