DNS Records
What is DNS Lookup?
DNS Lookup is a tool that queries Domain Name System servers to retrieve DNS records for a domain. DNS records contain important information about how a domain is configured, including mail servers (MX records), nameservers (NS records), IP addresses (A/AAAA records), and text records (TXT records) used for verification and security.
Why Use DNS Lookup?
DNS Lookup is essential for troubleshooting email delivery issues, verifying domain configuration, checking nameserver settings, validating SPF and DKIM records, and understanding how a domain is set up. It's used by system administrators, web developers, and IT professionals daily.
