We tested each nameserver and measured the following response times.

Nameserver IP address(es) Response time
ns1.vdc2.vn. 203.162.96.80 250ms
ns2.vdc2.vn. 203.162.96.80 240ms

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.

  • Nameserver ns1.vdc2.vn. (203.162.96.80) replied, but took too long (250ms). This will severely impact performance.

These are the locations and providers of your nameservers.

Nameserver Location ISP
ns1.vdc2.vn. IPv4: VN AS7643 - VNPT-AS-VN Vietnam Posts and Telecommunications (VNPT), VN
ns2.vdc2.vn. IPv4: VN AS7643 - VNPT-AS-VN Vietnam Posts and Telecommunications (VNPT), VN

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 (AS7643 - VNPT-AS-VN Vietnam Posts and Telecommunications (VNPT), VN). 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 (vdc2.vn). 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 (VN). 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)

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.
  • Consider giving the MX record for "ifbgroup.net.vn" a longer TTL, as those don't change often (1h+).
  • Consider giving the NS records for "ifbgroup.net.vn" a longer TTL, as those don't change often (1h+).
  • We detected a www record, but no record for your root. Consider adding a DNS record for "ifbgroup.net.vn" as an A record.
  • The active nameservers do not match your NS records. Please correct the NS records.

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 DNS record found on your zone apex (ifbgroup.net.vn). Consider adding a DNS record for "ifbgroup.net.vn" as an A record.
  • No IPv6 record has been found on the zone apex (ifbgroup.net.vn). 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.
  • SPF records have been found.
