This is a little DNS server inspired by nip.io and sslip.io that resolves any prefix-ww.xx.yy.zz-suffix.dns.example.com
to the ww.xx.yy.zz ipv4 address. In addition, it requests a *.dns.example.com wildcard certificate and
makes it available from https://key.example.com/?token=secret.
The only requirement is to create a DNS A record for dns pointing to this server along with a NS record DNS pointing to dns.example.com.
It caches certs, accounts and keys under ./cache.
