Domain DNS Checker

See the records a domain actually publishes right now — the A record a browser will follow, the nameservers answering for it, the MX records mail will use, and the TXT records that carry SPF and verification strings. Read from a public resolver, which is what the rest of the internet sees.

WHY IT DISAGREES WITH YOUR PANEL

Because caches have not caught up

A record you changed five minutes ago can still resolve to the old value for hours: resolvers keep the answer for as long as the record's TTL told them to, and the previous TTL is what applies to the change. If a checker shows the old value, the usual answer is that nothing is broken and the wait is not over.

  • The old TTL governs how long the old answer lives
  • Lower the TTL before a planned move, not after
  • Mail can follow a different path than the website

This reads the public DNS, so it can only see what is published: split-horizon setups, records behind a proxy, and anything served from an internal resolver will look different from inside your own network. It is a diagnostic, not a monitor — it answers what the record is now, not whether it changed overnight.
