Nameserver Location ISP
auth01.ns.eircom.net. IPv4: IE AS5466 - EIRCOM Internet House, IE
auth02.ns.eircom.net. IPv4: IE AS5466 - EIRCOM Internet House, IE

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.

  • All IPv4 nameservers are hosted by the same provider (AS5466 - EIRCOM Internet House, IE). Consider spreading the nameservers across multiple DNS providers for increased redundancy.
  • No DNSSEC records found. Consider enabling DNSSEC, as it provides a way to validate DNS responses for data integrity.
  • All the nameservers are being operated from a single domain (eircom.net). If that domain gets compromised or goes offline, the DNS will be unavailable. Consider spreading the nameservers across multiple domains.

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 (IE). 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.
