DNSSEC Configuration | DNSSEC Validation, Keys & Signature Analysis Tool

image.png

The platform available at https://dash.niamonx.io/dnssec_check — known as DNSSEC Configuration — is a DNSSEC validation and diagnostic tool within the NiamonX platform. It analyzes whether a domain is correctly protected with DNSSEC by checking DS records at the parent zone, DNSKEY records at the authoritative zone, RRSIG signatures, validation flags, DNS response status, authoritative name servers, IP nodes, and detected configuration issues.

The tool helps users understand whether a domain has a valid DNSSEC trust chain or whether DNSSEC is missing, incomplete, misconfigured, or failing validation.


Overview of the Service

DNSSEC Configuration is designed to analyze the DNSSEC state of a domain in a structured and readable way. DNSSEC helps protect DNS responses against tampering by using cryptographic signatures and a chain of trust from the parent zone to the domain’s authoritative DNS zone.

The tool checks several important parts of DNSSEC configuration:

The module is useful for DNS administrators, DevOps engineers, security teams, SOC teams, compliance teams, incident responders, domain owners, infrastructure engineers, and OSINT analysts.

It is especially helpful when users need to answer questions such as:


🔍 How the Tool Works

When a user enters a domain, DNSSEC Configuration performs DNSSEC-related DNS queries and analyzes the results.

Example input:

Domain: niamonx.io

Example summary result:

niamonx.io
DNSSEC is NOT correctly configured
Issues: 3
DNSKEY: 0
DS: 0
22:58:27

The tool may perform checks for:

The result is organized into multiple sections:


🧩 Supported Input

DNSSEC Configuration accepts domain names only.

Correct input examples:

niamonx.io
example.com
cloudflare.com
sub.example.com

Incorrect input examples:

https://niamonx.io
http://example.com
https://example.com/path
example.com/path
user@example.com
192.168.1.1
localhost

Interface guidance:

Enter the domain without the protocol (example.com).

Users should enter only the domain name, without http://, https://, path, query string, fragment, wildcard, or e-mail formatting.


📊 Summary Section

The Summary section provides a compact DNSSEC status overview.

Example:

niamonx.io
DNSSEC is NOT correctly configured
Issues: 3
DNSKEY: 0
DS: 0
22:58:27

Typical fields include:

Field Description
Domain The checked domain
Status DNSSEC validation result
Issues Number of detected configuration problems
DNSKEY Number of DNSKEY records found
DS Number of DS records found
Time Query or result timestamp

The Summary section is useful for quick triage. It immediately shows whether the domain appears to have a valid DNSSEC configuration or whether further investigation is needed.


✅ Status Validator

The tool provides a clear status result.

Example:

DNSSEC is NOT correctly configured

Possible high-level outcomes may include:

A valid DNSSEC configuration normally requires:

DS record in the parent zone
DNSKEY record in the authoritative zone
Valid RRSIG signatures
Successful validation
AD=true

If one or more of these components are missing or invalid, the domain may fail DNSSEC validation.


🧾 Domain Details

The detailed result section shows the checked domain and DNSSEC-related values.

Example:

Domain: niamonx.io
Status: DNSSEC is NOT correctly configured
Issues: 3
DNSKEY count: 0
DS count: 0
AD DNSKEY: false
AD DS: false
AD RRSIG: false
Authoritative NS: abdullah.ns.cloudflare.com, ashley.ns.cloudflare.com
IP nodes: 104.21.12.231, 172.67.153.184, 2606:4700:3033::6815:ce7, 2606:4700:3030::ac43:99b8

This section helps users understand both the DNSSEC state and the DNS infrastructure involved in the result.


🔐 DNSSEC Trust Chain

DNSSEC depends on a chain of trust.

A simplified trust chain looks like this:

Root zone
→ TLD parent zone
→ Domain DS record
→ Domain DNSKEY record
→ Signed DNS records
→ Validated response

For DNSSEC to validate correctly:

  1. The parent zone must publish a DS record for the domain.

  2. The domain’s authoritative zone must publish matching DNSKEY records.

  3. DNS records must be signed with valid RRSIG signatures.

  4. A validating resolver must be able to verify the signatures.

  5. The response should set AD=true when validation succeeds.

If the DS record is missing, the chain of trust cannot be established from the parent zone.

If DNSKEY records are missing, the domain zone cannot provide the public keys needed to validate signatures.

If RRSIG records are missing or invalid, DNSSEC-signed data cannot be validated.


🚨 Issues Section

The Issues section lists detected DNSSEC problems.

Example:

Issues
Total: 3

#1 Missing DNSKEY record
#2 Missing DS record
#3 No Authenticated Data (AD flag not set)

Issues help users quickly identify what needs to be fixed.

Common issues may include:

Each issue should be reviewed in the context of the domain’s DNS provider, registrar configuration, and authoritative zone settings.


🔑 DNSKEY Section

The DNSKEY section shows DNSKEY query details and DNSKEY records when available.

Example:

DNSKEY
AD: false
Status: 0
AD: false
CD: false
RD: true
RA: true
TC: false
Status 0
No DNSKEY records

DNSKEY records contain public keys used to validate DNSSEC signatures.

A DNSKEY record may include:

Field Description
Data DNSKEY record data
Flags Key role indicator
Proto DNSSEC protocol field
Algo Cryptographic algorithm
TTL Time to live

Example table when no records exist:

# Data Flags Proto Algo TTL
No DNSKEY records

If no DNSKEY records are found, the domain zone does not provide the public keys required for DNSSEC validation.


🧬 DNSKEY Flags

DNSKEY flags help identify the type of key.

Common values include:

Flag Meaning
256 Zone Signing Key, often called ZSK
257 Key Signing Key, often called KSK

The exact DNSSEC key structure depends on the DNS provider and deployment model.

In a typical DNSSEC configuration:

If DNSKEY records are missing, DNSSEC cannot be validated at the domain zone level.


🧾 DS Section

The DS section shows DS query results from the parent zone or authority response.

Example:

DS
AD: false
Status: 0
AD: false
CD: false
RD: true
RA: true
TC: false
Status 0

A DS record connects the parent zone to the child domain’s DNSKEY.

A valid DS record is required for a complete DNSSEC trust chain.

If the DS record is missing, the parent zone does not delegate DNSSEC trust to the domain.

Example issue:

Missing DS record

The DS section may also show authority records such as SOA, DS, RRSIG, or NSEC/NSEC3-related data.

Example authority output:

a0.nic.io. hostmaster.donuts.email. 1781729005 7200 900 1209600 3600

This information can help diagnose whether the parent zone returned a negative answer, an authority response, or related DNSSEC denial-of-existence data.


🧷 RRSIG Section

The RRSIG section shows signature query information.

Example:

RRSIG Query
AD: false
Status: 0
AD: false
CD: false
RD: true
RA: true
TC: false
Status 0
Response from 172.64.35.203.

RRSIG records contain cryptographic signatures for DNS records.

RRSIG is important because it proves that DNS records were signed by the domain’s DNSSEC keys.

A valid DNSSEC response generally requires:

If RRSIG validation fails or no authenticated data is returned, the tool may show an issue such as:

No Authenticated Data (AD flag not set)

🏁 AD Flag

AD means Authenticated Data.

Interface hint:

AD: Authenticated Data (server verified signatures).

Example:

AD DNSKEY: false
AD DS: false
AD RRSIG: false

When AD=true, the validating resolver indicates that DNSSEC validation succeeded for the response.

When AD=false, it may mean:

For a correctly validated DNSSEC response, AD=true is an important positive signal.


🚫 CD Flag

CD means Checking Disabled.

Interface hint:

CD: Checking Disabled (client requested to skip verification).

Example:

CD: false

When CD=true, the client asks the resolver not to perform DNSSEC validation.

When CD=false, DNSSEC validation is not intentionally disabled by the query.

The CD flag is useful for diagnosing whether DNSSEC failures are caused by validation behavior or by the underlying DNSSEC configuration.


🔁 RD and RA Flags

RD means Recursion Desired.

RA means Recursion Available.

Interface hint:

RD / RA: Recursion Desired / Available.

Example:

RD: true
RA: true

Meaning:

Flag Description
RD The client requested recursive resolution
RA The resolver supports recursive resolution

These flags help users understand how the DNS query was processed.


🧯 TC Flag

TC means Truncated.

Example:

TC: false

If TC=true, the DNS response was truncated. This can happen when the response is too large for the transport method and may require retrying over TCP.

A truncated DNSSEC response can affect diagnostics because DNSSEC records may be large.


📟 DNS Status Code

The Status field shows the DNS response code.

Interface hint:

Status: Response code (0=NOERROR).

Example:

Status: 0

Common DNS response codes include:

Code Meaning
0 NOERROR
1 FORMERR
2 SERVFAIL
3 NXDOMAIN
4 NOTIMP
5 REFUSED

A status of 0 means the DNS response itself returned NOERROR, but it does not automatically mean DNSSEC is correctly configured. DNSSEC may still be missing or unauthenticated.


🧭 Authoritative Name Servers

The DNS Chain section displays authoritative name servers for the domain.

Example:

Authoritative NS:
abdullah.ns.cloudflare.com
ashley.ns.cloudflare.com

Authoritative name servers are responsible for serving the domain’s DNS zone.

This information is useful for:

If DNSSEC is missing or broken, the authoritative DNS provider configuration should be reviewed.


🌐 IP Nodes

The DNS Chain section may also show IP nodes associated with the domain or authoritative resolution path.

Example:

IP nodes:
104.21.12.231
172.67.153.184
2606:4700:3033::6815:ce7
2606:4700:3030::ac43:99b8

IP nodes are useful for understanding the infrastructure returned by DNS resolution.

They may represent:

IP nodes should not be confused with DNSSEC keys. They are infrastructure addresses, not DNSSEC trust records.


💬 Query Comments

The tool may display comments showing where a response came from.

Examples:

DNSKEY Comment: Response from 173.245.58.71.
DS Comment: Response from 2a01:8840:a1::17.
RRSIG Comment: Response from 172.64.35.203.

These comments are useful for diagnostics because they show which resolver or server returned the response.

Response comments can help analysts identify:


🧠 Extended DNS Errors

Extended DNS Errors provide additional diagnostic information for DNS failures.

Interface hint:

Extended DNS Errors: Additional codes (RFC 8914) for failure diagnostics.

Extended DNS Errors may help explain:

If extended errors are present, they should be reviewed together with DNSKEY, DS, RRSIG, and response flags.


🕓 History of Domains

DNSSEC Configuration stores recently checked domains locally in the browser.

Example interface section:

History of domains
Filter...

History helps users:

Because history is stored locally, it may be removed when browser data is cleared, a private browsing session is used, or the user switches devices or browser profiles.

On shared or untrusted devices, users should clear local history after checking sensitive customer domains, investigation targets, or internal infrastructure.


📤 Copying and Exporting

DNSSEC Configuration supports copying and exporting results.

Available actions may include:

Copying and exporting are useful for:


🔎 Common Use Cases

DNSSEC Configuration Check

Verify whether a domain has DNSSEC enabled and correctly configured.

Domain Security Audit

Review DNSSEC status as part of a broader domain security assessment.

Registrar Configuration Review

Check whether DS records are published correctly at the parent zone.

DNS Provider Troubleshooting

Check whether DNSKEY and RRSIG records exist in the authoritative DNS zone.

Incident Response

Investigate whether DNS tampering protection is enabled for a domain involved in an incident.

Compliance Documentation

Document DNSSEC posture for compliance, audit, or risk management.

Migration Validation

Verify DNSSEC after changing DNS providers, registrars, nameservers, or signing configuration.

Broken DNSSEC Diagnosis

Identify whether validation failures are caused by missing DS, missing DNSKEY, invalid signatures, or resolver behavior.

Infrastructure Review

Map authoritative name servers and IP nodes involved in DNS resolution.

OSINT and Defensive Research

Check DNSSEC posture of domains during domain intelligence or external attack surface review.


A practical DNSSEC Configuration workflow should follow these steps.

1. Enter the Domain

Use only the domain name.

Example:

niamonx.io

Do not enter:

https://niamonx.io

2. Review the Summary

Start with the high-level status.

Example:

DNSSEC is NOT correctly configured
Issues: 3
DNSKEY: 0
DS: 0

This quickly shows whether DNSSEC is working or requires troubleshooting.


3. Review the Issues List

Check every issue reported by the tool.

Example:

Missing DNSKEY record
Missing DS record
No Authenticated Data (AD flag not set)

The issue list provides the most direct explanation of the DNSSEC problem.


4. Check DS Records

Review whether the parent zone publishes a DS record.

Example issue:

Missing DS record

If DS is missing, DNSSEC trust cannot be established from the parent zone.

This is often configured at the domain registrar.


5. Check DNSKEY Records

Review whether DNSKEY records exist in the authoritative zone.

Example issue:

Missing DNSKEY record

If DNSKEY is missing, the domain zone is not providing public keys for DNSSEC validation.

This is usually configured at the DNS provider.


6. Check RRSIG and AD Flag

Review whether signatures are present and whether authenticated data is returned.

Example:

AD RRSIG: false

If AD=false, the response was not authenticated by the validating resolver.


7. Review Authoritative Name Servers

Confirm that the expected name servers are authoritative.

Example:

abdullah.ns.cloudflare.com
ashley.ns.cloudflare.com

If the domain recently changed DNS providers, make sure the registrar and authoritative DNS provider are aligned.


8. Review IP Nodes

Check which IP nodes were returned.

Example:

104.21.12.231
172.67.153.184
2606:4700:3033::6815:ce7
2606:4700:3030::ac43:99b8

This helps understand the visible DNS infrastructure, although these IPs are not DNSSEC records.


9. Review Extended Errors

If extended DNS errors are present, use them to diagnose the failure.

Possible reasons may include:


10. Export or Copy Results

Save the DNSSEC diagnostic output for troubleshooting.

🧰 DNSSEC Troubleshooting Guide

Missing DS Record

Issue:

Missing DS record

Meaning:

The parent zone does not publish a DS record for the domain.

Possible causes:


Missing DNSKEY Record

Issue:

Missing DNSKEY record

Meaning:

The authoritative DNS zone does not publish DNSKEY records.

Possible causes:


AD Flag Not Set

Issue:

No Authenticated Data (AD flag not set)

Meaning:

The resolver did not return authenticated DNSSEC-validated data.

Possible causes:


Status 0 but DNSSEC Not Valid

A DNS status code of 0 means NOERROR, but this only means the DNS query succeeded.

Example:

Status: 0

This does not mean DNSSEC is correctly configured.

A domain can return NOERROR while still having:

Always review DNSSEC-specific fields, not only the DNS response status.


🚦 Server Errors and Retry Behavior

In some cases, the processing server may return an error.

Interface note:

In case of a processing server error and receiving a 500 error, please repeat your request several times.

A temporary server-side error may be caused by:

If this happens, repeat the request. If the issue continues, compare results with another DNSSEC validation method and contact support if needed.


📊 Interpreting Results Correctly

DNSSEC Configuration results should be interpreted carefully.

Important notes:

DNSSEC is one layer of domain security. It should be used together with HTTPS, HSTS, secure registrar accounts, MFA, DNS change monitoring, SPF, DKIM, DMARC, and proper access control.


When documenting DNSSEC status, use a consistent structure.

Example:

Domain: niamonx.io
Check time: 22:58:27

Status:
DNSSEC is NOT correctly configured

Issues:
1. Missing DNSKEY record
2. Missing DS record
3. No Authenticated Data (AD flag not set)

Counts:
DNSKEY: 0
DS: 0

Flags:
AD DNSKEY: false
AD DS: false
AD RRSIG: false

Authoritative name servers:
