DNS Lookup
Queries DNS records — A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV — for any domain using DNS-over-HTTPS. Paste a bare domain or full URL; pick Cloudflare or Google (or compare both side by side). Answers include TTL propagation tips, SPF/DKIM/DMARC parsing from TXT, structured SOA/CAA/SRV breakdowns, and dig-style or JSON export.
Runs 100% in your browser — nothing you paste leaves your device.

Notes
- Queries go directly from your browser to the resolver you pick (Cloudflare 1.1.1.1 or Google 8.8.8.8) over encrypted HTTPS.
- Answers are cached along the way: a record you just changed can keep showing its old value until the TTL expires.
- Runs 100% in your browser — nothing you paste leaves your device.
