How do I use the DNS propagation checker?
- Enter the domain (no https://).
- Choose the record type you changed.
- Compare the answers and TTLs, and check again after the TTL expires.
DNS propagation checker: frequently asked questions
How long does DNS propagation take?
Usually minutes to a few hours. It depends on the TTL of the old record, which is how long resolvers may cache it.
Why do resolvers show different answers?
Each resolver caches records independently until the TTL runs out, so some update sooner than others.
How can I make changes propagate faster?
Lower the TTL (e.g. to 300 seconds) a day before the change, make the change, then raise it again.
Which resolvers are checked?
Cloudflare 1.1.1.1 and Google 8.8.8.8, over DNS-over-HTTPS. Sites behind a CDN can legitimately return different IPs from each.
Why does my ISP still show the old site?
Your ISP’s resolver or your device may cache the old record. Flush your DNS cache or try mobile data.
Does it check nameserver changes at the registry?
Choose NS to see what resolvers return. Registry updates for .ae and other TLDs can take longer.
What is NXDOMAIN?
The domain or record does not exist in DNS.
Can I check email records?
Yes — choose MX for mail servers or TXT for SPF and verification records.
Why do results differ from another checker?
DNS and web responses are cached for their TTL and may differ by location. Our checks use Cloudflare’s 1.1.1.1 resolver.
Is the dns propagation checker free?
Yes. It is free with no sign-up and no usage limits for normal use.
