Independent networks
7 public DNS networks, queried in parallel
Every test query is answered by these unaffiliated resolvers on separate networks and infrastructure. When they agree, you can trust the result.

How it works
A test query for flag propagation check, done right
Most checkers query a single resolver or a set of geographically labelled servers behind the same anycast network. isPropagated queries genuinely independent DNS operators and compares both their records and their response flags.
Enter a domain and run the test query
Type any domain, pick a record type (A, AAAA, CNAME, MX, TXT, NS and more), then run a single test query that fans out to every network at once.
We query independent global networks
Instead of asking one resolver, we ask several unaffiliated public DNS networks in parallel — across North America, Europe and Asia — so no single cache can mislead you.
Compare records and DNS flags
Each network returns its answer plus the DNS response flags (AD, CD, RA, RD, TC). We check that both the records and the flags agree before calling a domain propagated.
Read the propagation verdict
A clear consensus score shows how many networks resolved the record and whether their answers match — so you know the moment a change is live everywhere.
How DNS propagation works for Netlify domains
Netlify is a web hosting and CI/CD platform. When you add, update, or delete a DNS record through Netlify, the change is applied to Netlify's authoritative nameservers immediately. However, resolvers around the world that have cached the previous record will not see the update until their cached copy expires — a period determined by the record's TTL (Time to Live).
Netlify DNS (when using Netlify's nameservers) uses short TTLs — typically 300 seconds — so propagation after record changes is fast. Netlify also auto-configures SSL and sets up DNS records automatically when you add a domain in its dashboard.
To monitor propagation in real time, enter your domain in the tool above and select the record type you changed. The check queries 7 genuinely independent DNS networks — not just geographically labelled servers behind the same infrastructure — and shows you exactly which resolvers have picked up the new value and which are still serving the old one.
Netlify DNS management and common propagation issues
DNS records for Netlify-managed domains are managed in the Netlify dashboard under Site configuration → Domain management → DNS settings. For domains using external nameservers, add the required A/CNAME record at your DNS provider, pointing to Netlify's load balancer.
Netlify SSL provisioning can fail if the DNS record is correct but has not fully propagated. After adding or changing the A record or CNAME for a Netlify site, use this checker to confirm propagation is complete, then trigger SSL re-provisioning from the Netlify domain settings.
FAQ
Common questions about netlify dns propagation checker
How do I check DNS propagation for my Netlify domain?
Enter your domain in the input above and select the record type you changed (usually A for host changes, MX for email changes, TXT for SPF/DKIM). Run the test query to see what all 7 independent resolvers currently return. When they all agree on the new value, propagation is complete.
Why is my Netlify DNS change not propagating?
The most common reasons are: the TTL on the previous record has not expired yet (resolvers cache the old value until then), the record was saved with an error in the value or hostname, or the change was made to the wrong zone (for example, editing records in Netlify when nameservers point elsewhere). Confirm the record is correct in the Netlify dashboard, then re-check with this tool after the TTL expires.
How long should I wait before assuming DNS propagation failed?
Wait at least one full TTL cycle beyond when you made the change. For a 3600-second TTL, that means at least 1 hour after saving. If records still differ across resolvers after two full TTL cycles, investigate the DNS configuration at the source rather than waiting longer.
Does this checker show DNS propagation from different countries?
Yes. isPropagated queries 7 independent resolvers operated by different organizations across North America (Google), Europe (AdGuard, DNS.SB), and Asia (Alibaba DNS, DNSPod). When all return the same value, your Netlify DNS change is live worldwide — not just in one region.
