DNS Health Check

A full audit of a domain's DNS configuration — redundancy, key records, email security and DNSSEC.

What this tool checks

NS — name server redundancy and diversity.
SOA — zone presence and consistency.
A / AAAA — IPv4 and IPv6 addresses.
MX — inbound mail servers.
SPF — authorised sender policy.
DMARC — protection against spoofing.
CAA — control over certificate authorities.
DNSSEC — cryptographic integrity of answers.

Why audit DNS?

An incomplete DNS setup leaves the domain open to email spoofing, cache poisoning and outages. A regular audit catches the gaps before anyone else does — especially after changing host or mail provider.
