Public DNS & IP Inspector Guide
Look up your public IP address and resolve DNS records using secure RFC 8484 DNS-over-HTTPS.
Overview
Perform RFC 8484 DNS-over-HTTPS lookups for A, AAAA, MX, TXT, and CNAME records directly from your browser, and inspect your client public IP address with zero command-line setup.

Real-World Examples
Frequently Asked Questions
What is DNS-over-HTTPS (DoH)?
DoH performs DNS queries over encrypted HTTPS connections (RFC 8484), preventing eavesdropping and manipulation by local network intermediaries.
Which DNS resolvers are queried?
Queries are sent to Cloudflare's public 1.1.1.1 DoH endpoint with standard JSON formatting.
Why do my updated DNS records take time to appear?
DNS records are cached by recursive resolvers for the duration specified in the record's TTL (Time to Live) setting.
