Reverse DNS Lookup

Find the PTR (reverse) record for any IPv4 or IPv6 address over DNS-over-HTTPS. Resolves the hostname an IP claims to map back to, straight from your browser.

Queries run live against Cloudflare's public DNS-over-HTTPS resolver (1.1.1.1). Nothing is sent to UniCybers servers and no lookups are stored. A PTR record is set by the IP block owner, so it may be missing, generic, or not match the forward record.
