What are DNSKEY Records?

DNSKEY (DNS Public Key) records contain public keys used in DNSSEC (DNS Security Extensions) to authenticate DNS data and prevent DNS spoofing attacks. They are essential for establishing a chain of trust in the DNS hierarchy.

Key Components:

  • Flags: Indicates the key type (256 for ZSK, 257 for KSK)
  • Protocol: Always 3 for DNSSEC
  • Algorithm: Cryptographic algorithm used (RSA, ECDSA, etc.)
  • Public Key: The actual cryptographic public key data

Key Types:

KSKKey Signing Key

Used to sign other DNSKEY records and establish trust with the parent zone

ZSKZone Signing Key

Used to sign all other records in the DNS zone
