What is DNS Lookup?

DNS Lookup is the process of querying Domain Name System servers to translate a domain name (like www.example.com) into its corresponding IP address or to retrieve other DNS records. This translation is vital because while humans use domain names, computers communicate using IP addresses.

  • Security Checks: Detect suspicious DNS records that may indicate domain hijacking or misconfiguration.
  • Website Setup: Confirm your domain is correctly pointing to your web host or email server.
  • Network Diagnostics: Verify the current state of DNS records to ensure reliability.
