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.
What is an AAAA record and when does propagation matter?
An AAAA record maps a domain or subdomain to an IPv6 address — the 128-bit successor to IPv4. As IPv6 adoption grows, more hosting providers, CDNs, and cloud platforms issue dual-stack IPv6 addresses alongside IPv4, and you may need to add or update an AAAA record when enabling IPv6 on your server or switching to a provider that assigns a different IPv6 prefix.
AAAA record propagation follows the same TTL-driven rules as A records. Until every resolver expires its cached answer and fetches the new AAAA value from your authoritative server, a subset of IPv6-capable clients will reach the old address. On dual-stack networks, this is less visible to end users (the A record may succeed even if AAAA is stale), but it can cause connection resets on IPv6-only clients or reveal split-brain configurations.
Run this check after adding a new IPv6 address, changing your CDN's IPv6 range, or enabling IPv6 on a load balancer to confirm every network returns the correct address before you rely on it.
AAAA vs A propagation: what to watch for
The AAAA check works identically to an A check — it sends a DNS query for type 28 (AAAA) and compares the IPv6 addresses returned by each resolver. A fully propagated AAAA record means all 7 networks return the same IPv6 address and agree on the DNSSEC (AD) flag.
One nuance: some resolvers or networks are IPv4-only infrastructure even if they serve AAAA queries. An NXDOMAIN response on one resolver may mean that resolver has not yet seen the record, or that the name truly has no AAAA record — check the count of resolvers that resolve versus return NXDOMAIN to tell the difference.
FAQ
Common questions about aaaa record propagation checker
How do I add an AAAA record and confirm it propagated?
Log in to your DNS provider, create a new AAAA record with your server's IPv6 address and a TTL of 3600 (or lower if you need fast rollback), then use this checker. Enter the domain, select AAAA, and run the test query. Once all 7 networks return the same IPv6 address, the record is live everywhere.
My AAAA record propagated but IPv6 still does not work. Why?
DNS propagation is only one part of IPv6 connectivity. The server must also be listening on that IPv6 address, the firewall must allow IPv6 traffic, and the network path must be IPv6-capable end to end. Use the checker to confirm the DNS side is correct, then debug the server configuration separately.
Can I have both A and AAAA records on the same domain?
Yes. A domain with both an A and an AAAA record is called dual-stack. Modern operating systems prefer IPv6 when available (RFC 6724 / "Happy Eyeballs"). You can check each record type independently using this tool — just select A or AAAA from the dropdown.
How long does AAAA record propagation take?
Exactly as long as the TTL on the previous record. If the old AAAA record had a TTL of 3600, expect up to 1 hour. If you are adding a brand-new AAAA record where none existed before, resolvers will propagate the new record much faster because there is no stale cache to expire.
