Monitoring that explains what happened
DNS monitoring for records that matter
DNS changes can redirect a website or break email while the server itself remains healthy. Monitor important records alongside HTTP and SSL checks.
Choose a record with a purpose
Use A or AAAA for an address, CNAME for an alias, MX for mail routing, NS for delegated nameservers or TXT for published verification and policy records.
Understand change before reacting
A record change can be intentional. Compare the result with your DNS provider and deployment schedule. A successful lookup proves that this resolver received an answer, not that every resolver has refreshed its cache.
Complete the diagnostic picture
Pair DNS checks with website availability and certificate monitoring. Email domains also benefit from SPF and DMARC checks to identify missing or conflicting policy records.
Common questions
Does this show global propagation?
No. Results reflect this service’s DNS resolution. Resolver caches and TTLs can produce different answers elsewhere.
Will the monitor change my DNS?
No. It reads public records; it does not modify your DNS provider account.
