We detected the following errors or warnings about your DNS configuration. These caused your DNS rating to be lowered. Resolving these will grant a higher DNS Spy rating for your domain.

  • We only detected 1 MX record. Multiple MX records (or multiple IPs behind the MX record) provide redundancy and a more robust e-mail setup.

We detected some possible recommendations for you to consider. No penalties were given for these, but resolving them can give you a higher DNS score.

  • No DMARC records have been found. Consider configuring DMARC for improved e-mail authentication.
  • No IPv6 record has been found on the zone apex (oas.psu.ac.th). Consider enabling IPv6 in the infrastructure by adding an AAAA record on this domain.

Good news, we detected the following achievements in your DNS configuration. Each of these checks has increased your DNS Spy score.
