DNS MONITORING IN PRACTICE
Find the evidence behind a DNS change.
Six practical guides with fictional examples, clear coverage and a starting point for your own domain. Ongoing monitoring is available through the Free plan.
DNS change monitoring: understand what changed
Track DNS record changes with a before-and-after change log across nameservers and resolvers. Review incidents and recovery for enabled monitors.
DNS propagation vs. incident: read conflicting answers
Distinguish cached DNS answers from missing records, source failures and unexpected authoritative differences before declaring a DNS incident.
Cloudflare DNS drift: compare configuration and served answers
Compare accepted Cloudflare DNS configuration, current provider settings and public DNS evidence without confusing proxied answers with origin addresses.
DNSSEC monitoring: follow keys, delegation and validation evidence
Investigate DNSSEC evidence across parent delegation, published keys and resolver responses, with clear limits around signature validation.
SPF and DMARC change monitoring for your sending domain
Detect changes to sender authorization and DMARC policy records in your own domain without assuming DNS checks prove email deliverability.
DNS monitoring for MSPs: give each customer a clear scope
Organize customer DNS monitoring by organization, select critical resources and investigate changes with explicit coverage and access boundaries.
