The DNS Propagation Checker queries a domain's A, AAAA, CNAME, MX, TXT and NS records from multiple global DNS resolvers at once, so you can confirm whether a change you made has spread across the internet. When you switch hosting, update an IP address, add an SPF record, or point a domain to a new server, DNS changes do not update everywhere instantly; this tool shows you, resolver by resolver, exactly what each region is currently returning.
It is a must-have for developers, sysadmins, and site owners in Cambodia and worldwide who need to know a migration is safe to complete. This free tool by Hosting Cambodia lets you enter a domain, choose a record type, and see live results from resolvers in different locations, so you can tell the difference between a change that is still propagating and one that is genuinely misconfigured.
Frequently asked questions
How long does DNS propagation usually take?
It typically completes within a few minutes to a few hours, but can take up to 24 to 48 hours depending on the record's TTL and how aggressively resolvers cache. Lower TTLs propagate faster.
Which DNS record types can I check?
You can check A and AAAA (IPv4 and IPv6 addresses), CNAME aliases, MX mail records, TXT records like SPF and DKIM, and NS name server records.
Why do different resolvers show different results?
During propagation, some resolvers still serve a cached old value while others have picked up the new one. Once all locations show the same record, propagation is complete.
