Let me introduce you to a new program, an experimental authoritative #DNS server intended for dynamic answers. It is just for fun and it does not pretend to replace existing programs. But you may want to read its source code, or use its online demo, at dyn.bortzmeyer.fr.
(Also botsin.space/@DNSresolver/1083…)
DNS resolver bot (@DNSresolver@botsin.space)
@bortzmeyer@mastodon.gougere.fr Possible queries: hello/TXT to have a greeting. ip/TXT,A,AAAA to have the IP address of the client. date/TXT to have the date. random/TXT,A,AAAA to have a random integer or address.botsin.space
