The DNS Checker

At the heart of DNS Check is a DNS record checking tool, which compares the DNS records you enter to what DNS servers are returning in response to queries. If there's an issue, the record checking tool enables you to identify it quickly. Detectable issues include:

  • Unresponsive name server
  • The wrong IP address returned
  • Missing DNS record
  • Duplicated DNS records
  • Wrong MX record preference returned
  • Mismatched forward and reverse DNS records
  • IP addresses removed from SPF record
  • Out-of-sync name servers
  • Invalid SPF record
