DNS Lookup

Queries DNS records for a domain via public DNS-over-HTTPS (DoH) resolvers and shows the answers in a card per record type. Pick Google, Cloudflare, or AliDNS as the resolver, toggle the record types you want, and run a lookup. Provider, selected record types, and the last 20 queried domains are saved locally (IndexedDB) between visits.

1. Pick a DNS Provider (Google dns.google, Cloudflare cloudflare-dns.com, or AliDNS dns.alidns.com). 2. Toggle the record types you want: A, AAAA, MX, CNAME, TXT, NS, SOA (A, AAAA, MX, TXT are on by default). 3. Enter a domain and click Lookup or press Enter. 4. A card appears per record type with each answer's type, data, and TTL in seconds. Recent lookups are saved as clickable history chips.

Google is queried at https://dns.google/resolve?name=...&type=..., Cloudflare at https://cloudflare-dns.com/dns-query (with accept: application/dns-json), AliDNS at https://dns.alidns.com/resolve. Numeric types from the JSON Answer are mapped to names (1=A, 28=AAAA, 15=MX, 5=CNAME, 16=TXT, 2=NS, 6=SOA; anything else shows as TYPE<number>). A Status != 0 with no Answer is reported as No records found. Settings persist under the dns-lookup-settings key.
