Looks up DNS records over DNS-over-HTTPS (Cloudflare 1.1.1.1, Google 8.8.8.8 or Quad9) straight from the Worker: the common set (A, AAAA, CNAME, MX, NS, TXT, SOA), the full set (adds SRV, CAA, DS, DNSKEY, HTTPS, SVCB, PTR, NAPTR, TLSA) or a single type. Records are parsed (MX priority, SOA timers, SRV/CAA/HTTPS parameters, DNSKEY roles), CNAME chains are followed, NXDOMAIN and resolver errors are explained, DNSSEC validation (AD flag) can be requested and common mistakes (multiple SPF records, missing MX) are flagged. The raw JSON answers are the secondary output. Names are sent to the chosen resolver; nothing is stored.
