How to Look Up DNS Records for Free
1. Enter a domain name for a forward lookup, or an IP address for a reverse lookup.
2. Pick which record types to query - A, AAAA, MX, TXT, and NS are selected by default.
3. Click Lookup DNS to see the records, WHOIS registration info, and the resolving server's geographic location.
4. Turn on Advanced Settings to query over a specific protocol, lookup mode, or custom DNS server instead of the defaults.
Lookups Run From Your Browser, Through Public Services
DNS queries are sent directly from your browser to a public DNS-over-HTTPS resolver (Google by default, or Cloudflare if you pick 1.1.1.1; the propagation check asks both); choosing UDP or TCP sends them to dnsjson.com instead. IP location lookups go to ipwho.is and WHOIS lookups to whoisjson.com. The resolver, dnsjson.com and whoisjson.com see the domain you enter, ipwho.is sees the DNS server's IP, and every one of them sees your own IP address. There is no Puenbann server in the middle, and only your local lookup history is stored, entirely in your browser.
