  • Expiry date and days remaining
  • Issuer and certificate chain
  • Subject Alternative Names (SANs)
  • Validity status (valid / expiring soon / expired)

DNS Lookup & Propagation

Query A, AAAA, MX, TXT, CNAME, and NS records. We check four major public resolvers (Cloudflare, Google, Quad9, OpenDNS) so you can see if DNS changes have propagated.

  • A, AAAA, MX, TXT, CNAME, NS records
  • Propagation across 4 public resolvers
  • TTL values for each record
  • Clean NXDOMAIN detection
