DNS Lookup
The DNS Lookup tool lets you query public DNS records for any domain or hostname. Select from common record types — A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV, and PTR — and see results including record values, TTLs, and priorities where applicable. Specify an optional custom resolver to test against specific nameservers like Google DNS (8.8.8.8) or Cloudflare (1.1.1.1). Use this tool when troubleshooting email delivery issues (MX and TXT/SPF records), verifying DNS propagation after changes, auditing domain security configurations (CAA records), or simply checking how a domain resolves from the public internet. Results are displayed in a clean table with copy-to-clipboard support for each value. Shareable URLs let you send lookup results to colleagues. All queries are processed server-side and no personal data is stored.
