Full DNS lookup over Cloudflare 1.1.1.1 DNS-over-HTTPS. Queries any subset of A, AAAA, MX, TXT, NS, CNAME, SOA, PTR, SRV, CAA, DNSKEY, DS, TLSA, HTTPS, and SVCB records and returns results grouped per type with TTLs plus a flat list. Works as a dig/nslookup replacement, MX checker, SPF + DMARC TXT inspector, CAA/DNSSEC inspector, nameserver finder, or CDN-routing detector.
