DNS Propagation Checker
DNS Propagation compares answers from multiple public resolvers. It helps confirm whether a change is broadly visible or still cached differently around the internet.
What It Compares
- A, AAAA, CNAME, MX, TXT, and other common DNS records.
- Answers from major public resolvers.
- Resolver errors, no-answer states, and differing responses.
When To Use It
Use it after changing DNS records, moving a website, updating MX records, validating TXT ownership records, or troubleshooting users who see different answers from different networks.
Reading The Result
- Matching answers usually mean the change is widely visible.
- Mixed answers often point to TTL cache timing.
- If every resolver fails, review the authoritative DNS setup.
