Have your DNS records changed?

Monitor DNS records for unexpected changes that could break your site, email, or services.

What are DNS Records?

DNS (Domain Name System) records are the configuration entries that tell the internet where to send traffic for your domain. A records point to your web server, MX records route email, CNAME records create aliases, and TXT records hold verification and authentication data like SPF and DKIM.

A single unexpected DNS change can take your website offline, break email delivery, or redirect traffic to the wrong server. Changes can happen through registrar account compromise, accidental edits, or propagation issues — and they often go unnoticed until something breaks.

DNS Monitor checks all your record types hourly, detects changes with diff views, and tracks DNS propagation across global resolvers — so you catch problems before they affect your users.
