DNS change monitoring

Know the momentyour DNS changes.

Domain Lab records every DNS record of your domains and alerts you when anything changes — with before/after diffs, full history, and an AI explanation of whether the change looks routine or dangerous.

DNS changes are silent until something breaks

A changed A record can send your traffic somewhere else. A modified MX record can reroute your email. An unexpected nameserver change can be the first visible sign of a domain hijack — or just a teammate's undocumented migration. Either way, DNS changes rarely announce themselves: you find out when customers do.

Domain Lab keeps an independent, timestamped record of your DNS state, so "what changed, and when?" always has an answer.

How DNS monitoring works

Every record, diffed

A, AAAA, MX, NS, TXT, CNAME and more are captured on every scan. When something changes, you see the exact before/after values — like a code diff for your DNS.

AI judgment on every change

Routine SSL renewal? Planned migration? Or a suspicious nameserver swap? Domain Lab's AI reviews each change in context and tells you in plain English whether it deserves attention.

Noise-filtered alerts

Domain Lab suppresses known-noisy patterns — like Cloudflare edge-IP rotation — so an alert means something actually changed, not that a CDN shuffled its anycast pool.

Full change history

Every event is stored on a timeline per domain. Need to roll back? The record you had before the change is right there.

Part of complete domain monitoring

DNS monitoring works alongside domain expiration monitoring, SSL certificate monitoring, and WHOIS change monitoring in one event feed — with alerts to email, Slack, Pushover, and webhooks, plus a REST API for automations and AI agents.

Frequently asked questions

Which DNS record types does Domain Lab monitor?

Domain Lab captures the full public DNS state of your domain on each scan — including A, AAAA, MX, NS, TXT, and CNAME records — and stores each version so changes appear as before/after diffs.

How fast will I know about a DNS change?

Domains are re-scanned daily. When a change is detected it becomes an event immediately and notifications go out through your chosen channels — email, Slack, Pushover, or webhooks.

Can DNS monitoring detect a domain hijack?

Unexpected nameserver or A record changes are among the earliest visible signs of a hijack. Domain Lab alerts on those changes and its AI review flags combinations that look suspicious rather than routine.

Will I get spammed by CDN IP rotations?

No. Domain Lab filters known-noisy patterns such as Cloudflare edge-IP rotation, so alerts fire on meaningful changes rather than infrastructure churn.

Do I need to change my nameservers or install anything?

No. Monitoring is completely external and read-only — add your domain and Domain Lab observes its public DNS from the outside, regardless of where the domain is registered or hosted.
