DANE TLSA Checker

Check DANE TLSA records for a domain

About DANE TLSA Checker

DANE (DNS-based Authentication of Named Entities) uses DNSSEC to bind TLS certificates to domain names via TLSA records. Our DANE TLSA Checker queries the DNS for TLSA records, validates their usage, and shows whether a domain has DANE enabled. This eliminates reliance on external Certificate Authorities for trust decisions.

How to Use

1Enter the domain name you want to check for DANE TLSA records.
2Click "Check" to query the DNS for TLSA records.
3View the TLSA record details and DANE status for the domain.

Use Cases

•Verify DANE TLSA records after publishing them in DNS
•Audit domains for DANE compliance and proper TLSA configuration
•Reduce CA dependency by using DANE-based certificate validation
•Troubleshoot DANE-related connection issues for email and web servers

Frequently Asked Questions

DANE (DNS-based Authentication of Named Entities) is a protocol that uses DNSSEC to associate TLS certificates with domain names, allowing administrators to specify which CA may issue certificates for their domain.

Yes, DANE relies on DNSSEC to authenticate TLSA records. Without DNSSEC, TLSA records can be spoofed, defeating the purpose of DANE's security guarantees.

TLSA records contain four fields: usage (how the cert is associated), selector (which part of the cert is matched), matching type (hash type), and the certificate association data.

Tips & Best Practices

•Use DANE to add DNS-based trust anchors for certificate validation
•Configure TLSA records correctly for your certificate chain
•Monitor DANE record validity and certificate association
•Combine DANE with DNSSEC for maximum security
