Frequently Asked Questions
Why do some locations show different DNS results?
Each DNS resolver caches records independently based on the TTL. Until a resolver’s cache expires and it fetches the updated record from the authoritative server, it returns the old value. This is why you may see “Propagated” in some regions and “Different” in others — the old cache hasn’t expired at those locations yet.
What does "No record" mean in a DNS propagation check?
A “No record” result means the resolver returned NXDOMAIN or an empty answer for that record type. This may mean the record hasn’t been created yet, was deleted, or the new record hasn’t reached that resolver’s cache. Compare with other locations — if most show a value and only a few show “No record”, propagation is still in progress there.
Why is my DNS still showing the old record?
Your local DNS resolver or ISP has cached the old record and the TTL hasn’t expired yet. Try flushing your local DNS cache, or use a public resolver like 1.1.1.1 or 8.8.8.8 to see updated results faster. If your record is already updated at the authoritative nameserver, you simply need to wait for the TTL to expire globally.
Does this DNS propagation checker use real DNS servers?
Yes. Our tool performs real DNS lookups using DNS over HTTPS (DoH) from each location’s resolver — not simulated or cached results from our own servers. Every result reflects an actual live query to that resolver at the time you run the check. The specific resolver and IP are shown on each result card.
How is a global DNS propagation check different from a regular DNS lookup?
A standard DNS lookup queries only your local resolver, which may return a cached result. A global propagation check queries multiple resolvers in different geographic regions simultaneously, showing you how DNS is actually resolving for users in each part of the world right now — not just what your local network sees.
