Frequently Asked Questions
Why do DNS updates take time to propagate?
DNS changes depend on Time-to-Live (TTL) cache settings. Until the TTL expires, resolvers around the world will continue serving cached records.
Does this check query live DNS resolvers?
Yes. All records are resolved dynamically by querying live name servers in real-time.
