DNS Lookup

About DNS records

This tool lists DNS records for a domain name—such as A, AAAA, MX, TXT, CNAME, and NS. The results help you verify mail routing, authentication records (for example SPF and DKIM), and subdomain configuration.

When to use it

  • Confirm that changes to DNS have propagated after an update.
  • Troubleshoot email delivery by checking MX and TXT records.
  • Investigate website or TLS issues by reviewing A/AAAA and CNAME consistency.
