Compare A, AAAA, CNAME, MX, NS, or TXT answers across six independent named public recursive resolver operators.
Only public web targets are accepted. Private and reserved network ranges are blocked.
Spot resolver disagreement after a DNS change and see whether responding operators have converged on the same answer.
Use this check when you need a focused answer about the specific signal described above rather than a broad, unexplained SEO score.
Queries Google, Cloudflare, Quad9, OpenDNS, AdGuard DNS, and Control D. This is resolver comparison rather than a fabricated geographic propagation map.
Because website responses can change by time, location, resolver, or server configuration, treat the result as a current observation of the submitted public target.
