DNS Toys: Useful utilities and services over DNS

That is creative. One feature request to consider would be using records off dns.toys instead of requiring @dns.toys for people behind firewalls that must route their request through their recursive servers. e.g. dig mumbai.time.dns.toys

Some functions obviously will not work the same way such as myip.dns.toys that would instead show the recursive DNS server SNAT IP unless their server supports edns client subnet forwarding.
