How the check works
The tool asks 12 public DNS resolvers directly — including Google, Cloudflare, Quad9, AdGuard, Gcore, AliDNS (China), Yandex and Hurricane Electric — for the record you choose. Answers are compared with the most common result:
- Matches — the resolver has the same answer as the majority.
- Different — the resolver still has an older (cached) answer.
- NXDOMAIN / no record — the name or record does not exist for that resolver.
How long does propagation take?
It depends on the TTL of the old record. With a TTL of 300 seconds, changes spread within minutes; with 86,400 seconds (one day) it can take up to 24–48 hours. Lower the TTL a day before a planned change to make the switch fast.
See every record type for a domain at once with the DNS Records Checker.
Frequently asked questions
Can I speed up DNS propagation?
Not after the change. Before a change, lower the TTL so resolvers refresh sooner. Some resolvers, such as Google and Cloudflare, also offer a cache flush page.
Why do some resolvers show different results?
They cached the old answer and will update when its TTL runs out. Geo-DNS and CDNs can also return different IPs by location on purpose.
Which record types are supported?
A, AAAA, CNAME, MX, NS and TXT.
