Check DNS propagation across major resolvers
What is DNS propagation?
When you change a DNS record, authoritative servers update immediately — but recursive resolvers worldwide cache the old answer until the record's TTL expires. "Propagation" means waiting for those caches to refresh and return the new value.
DNS Buddy does not guess propagation from a world map. It shows you what each major public resolver returns right now, which is what matters when debugging a cutover or a support ticket that says "DNS still looks wrong."
How to verify propagation with DNS Buddy
- Open DNS Lookup and enter the hostname you changed.
- Select the record type (A, AAAA, CNAME, MX, TXT, etc.) and run the query.
- Compare answers from Google, Cloudflare, Quad9, and OpenDNS. Matching values mean major resolvers agree.
- If one resolver is stale, wait one TTL cycle and re-check. Lower TTL before migrations to speed this up.
DNS Buddy vs geographic propagation maps
Tools like WhatsMyDNS and DNSChecker show pass/fail dots on a world map. That is useful for a visual gut-check. DNS Buddy is built for operators who need the actual record values, bulk verification across hundreds of domains, and WHOIS context in the same session.
