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.

  • No DNSSEC records found. Consider enabling DNSSEC, as it provides a way to validate DNS responses for data integrity.

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.

  • All IPv4 nameservers appear to be hosted in the same country (US). You might want to consider spreading the nameservers geographically.
  • No CAA records found. Consider adding CAA records, as it adds increased security by limiting which Certificate Authorities can issue certificates for this domain. (more info)

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

  • You have more than 1 nameserver.
  • The IPv4 nameservers are distributed among multiple providers.
  • The IPv6 nameservers are distributed among multiple providers.
  • The IPv6 nameservers are distributed across multiple locations.
  • The nameservers are being operated from multiple domains (dynect.net, ultradns.net, ultradns.org, ultradns.info, amazonaws.com).

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.

  • Consider giving the NS records for "eu-west-1.compute.amazonaws.com" a longer TTL, as those don't change often (1h+).

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 SPF records were found. SPF records limit which IPs are allowed to send mail from this domain. Even if this domain doesn't send e-mails, you should set up SPF to confirm it will never send e-mail, to prevent spoofing.
  • No DMARC records have been found. Consider configuring DMARC for improved e-mail authentication.
  • No DNS record found on your zone apex (eu-west-1.compute.amazonaws.com). Consider adding a DNS record for "eu-west-1.compute.amazonaws.com" as an A record.
  • No IPv6 record has been found on the zone apex (eu-west-1.compute.amazonaws.com). 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.

  • Your SOA serial number follows the best practice YYYYMMDDxx format.
  • The active nameservers match the NS records.
  • The DNS records appear to be RFC compliant.
