DNS Lookup Online

Query common Domain Name System records for a domain and inspect how its DNS is configured. DNS connects domain names with services such as web servers and email systems through different record types.

How to perform a DNS lookup

  1. Enter the domain or hostname you want to inspect.
  2. Select or run the available DNS query.
  3. Review the records returned by the lookup.
  4. Compare them with the configuration expected from your hosting, email or DNS provider.

Common DNS record types

A and AAAA records map names to IP addresses. CNAME creates an alias to another hostname. MX records identify mail servers, while TXT records are commonly used for verification and email-related policies. NS records identify authoritative nameservers.

DNS changes can take time

Cached records and TTL values can mean that a recent DNS change is not visible everywhere immediately. If you have just modified a record, compare results again after caches have had time to refresh.

FAQ
