When you’re setting up a device for testing, sometimes you need to set up a DNS server. And when you do, you don’t want to be messing around with DNS configuration files.
MiniDNS is a very simplistic DNS server that responds to all DNS queries with a single IPv4 address. Just provide it with the IP address you want requests to resolve to, and you’re up and running:
# minidns 22.214.171.124
