How to use this free DNS checker
DNS connects domain names with services such as websites and email. Enter the domain or URL above and review the returned records and status details. The results reflect the information available when the check runs.
Understanding your DNS results
A records map names to IPv4 addresses, AAAA records to IPv6 addresses, and NS records identify authoritative nameservers.
DNS changes can take time to propagate because recursive resolvers cache earlier responses according to TTL values.
