DNSSEC Checker

Use the DNSSEC Checker to test whether a domain is protected with DNSSEC and whether its DNSSEC validation chain is working correctly. DNSSEC helps protect DNS responses from tampering by adding cryptographic validation to DNS records.

If you manage a domain, DNS provider, registrar settings, or security-sensitive website, checking DNSSEC can help you confirm whether the domain’s DNS security configuration is valid.

If you need to verify your own network address before running DNS diagnostics, you can view the IP address your browser is using first.

What Is DNSSEC?

DNSSEC, short for Domain Name System Security Extensions, is a security extension for DNS. It helps verify that DNS responses are authentic and have not been modified in transit.

Normal DNS translates domain names into IP addresses, but it does not provide strong built-in proof that the response has not been tampered with. DNSSEC adds digital signatures so validating resolvers can confirm that DNS records came from the correct authoritative source.

Why DNSSEC Matters

DNSSEC helps protect domains from certain DNS-based attacks, including forged DNS responses and cache poisoning. It is especially useful for domains that require stronger trust in DNS resolution.

DNSSEC can help with:

• Protecting DNS records from tampering.
• Improving trust in DNS responses.
• Supporting security compliance requirements.
• Reducing risk from DNS spoofing and cache poisoning.
• Strengthening the domain’s overall security posture.

How to Use the DNSSEC Checker

Using the IPMYP DNSSEC Checker is simple and does not require DNS command-line tools.

1. Enter a domain name, such as example.com.
2. Run the DNSSEC check.
3. IPMYP checks the domain’s DNSSEC-related records and validation status.
4. Review whether DNSSEC appears enabled, valid, broken, or missing.
5. Use the result to troubleshoot registrar, DNS provider, DS, DNSKEY, or signature problems.

For a broader diagnostic review that includes DNS records, SSL, WHOIS, Ping, MTR, and other tools, use the main online network tools hub.

What Does a DNSSEC Report Show?

A DNSSEC report may include several important validation details.

• DNSSEC Status: Whether DNSSEC appears enabled, disabled, valid, or broken.
• DS Records: Delegation Signer records published at the parent zone.
• DNSKEY Records: Public keys published in the authoritative DNS zone.
• RRSIG Records: Digital signatures for DNS records.
• Validation Chain: Whether trust can be followed from the parent zone to the domain.
• Errors: Problems such as missing DS, mismatched keys, expired signatures, or broken delegation.

DNSSEC, DS Records and DNSKEY Records

DNSSEC depends on a chain of trust. Two important parts of this chain are DS records and DNSKEY records.

DS Record

A DS record is published at the parent zone, usually through the domain registrar. It points to the DNSKEY used by the domain’s authoritative DNS zone.

DNSKEY Record

A DNSKEY record is published in the domain’s DNS zone. It contains the public key used to validate DNSSEC signatures.

If the DS record at the registrar does not match the DNSKEY record at the DNS provider, DNSSEC validation can fail and the domain may become unreachable for validating resolvers.

When Should You Check DNSSEC?

DNSSEC should be checked whenever DNS security, registrar changes, DNS provider migrations, or validation errors are involved.

• After enabling DNSSEC for a domain.
• After changing DNS providers.
• After changing name servers.
• After updating DS records at the registrar.
• When a domain works for some users but fails for validating resolvers.
• During security audits or compliance checks.

Common DNSSEC Problems

DNSSEC is powerful, but misconfiguration can cause serious DNS resolution issues. A broken DNSSEC chain can make a domain fail for users whose resolvers validate DNSSEC.

• DNSSEC is enabled at the registrar but not configured at the DNS provider.
• DS records do not match DNSKEY records.
• DNS signatures have expired.
• Name servers were changed but old DS records remained.
• DNSSEC was disabled at the DNS provider but not at the registrar.
• The domain has inconsistent DNSSEC data across authoritative name servers.

DNSSEC and DNS Delegation

DNSSEC depends on correct delegation. If the domain’s name servers, DS records, or DNSKEY records are inconsistent, validation may break.

When troubleshooting DNSSEC, it is useful to also check DNS Delegation and DNS Propagation to confirm that the correct DNS provider is active and visible.

DNSSEC and Other DNS Security Records

DNSSEC protects DNS integrity, but it does not replace other security-focused DNS records. For example, CAA records control SSL certificate issuance, while SPF, DKIM, and DMARC help protect email identity.

For a more complete domain security audit, check CAA Records and Email Security Records as well.

Best Practices for DNSSEC

• Enable DNSSEC only when your registrar and DNS provider support it properly.
• Make sure DS records match the DNSKEY records from your DNS provider.
• Check DNSSEC after changing name servers or DNS providers.
• Remove old DS records before disabling DNSSEC or moving DNS providers.
• Monitor DNSSEC validation after key rollovers.
• Test DNSSEC after every major DNS migration.

Frequently Asked Questions

What does a DNSSEC Checker do?

A DNSSEC Checker tests whether a domain has DNSSEC enabled and whether the DNSSEC validation chain is working correctly.

What happens if DNSSEC is broken?

If DNSSEC is broken, some validating resolvers may refuse to resolve the domain, causing the website, email, or subdomains to appear unreachable for some users.

Is DNSSEC the same as SSL?

No. DNSSEC protects DNS responses from tampering. SSL/TLS protects the connection between a browser and a website.

Should every domain enable DNSSEC?

DNSSEC can improve DNS security, but it must be configured carefully. Incorrect DNSSEC setup can cause domain resolution failures.

What should I check before enabling DNSSEC?

Check that your registrar and DNS provider support DNSSEC, then verify DS records, DNSKEY records, and name server delegation after enabling it.
