DNS security

DNSSEC checker

Check DS and DNSKEY records and ask a validating public resolver whether the domain's DNSSEC chain authenticates correctly.

Quick guide

What DNSSEC protects

DNSSEC adds cryptographic signatures to DNS so validating resolvers can detect forged or altered answers. A normal chain of trust links a parent DS record to DNSKEY records in the child zone.

DNSSEC does not encrypt DNS traffic or make a website itself secure. It authenticates DNS data.

DS

A parent-zone record that points to the child zone signing key.

DNSKEY

The public keys published by the signed DNS zone.

Validated

A validating resolver authenticated the signed response through the chain of trust.

How it works

IPGetter checks DS and DNSKEY records and asks a validating public resolver whether the signed DNS chain can be authenticated.
