DNS Lookup provides details about a domain’s DNS records, including A, MX, CNAME, and TXT entries. This offers insight into how a domain is configured and which servers handle its email or web hosting. For troubleshooting or server migrations, understanding DNS entries is crucial: you can confirm if mail is routed properly or whether subdomains point to the correct host. DNS Lookup helps diagnose slow loading times, reveals if a record is missing, or alerts you to potential misconfigurations. Whether you’re checking IP addresses, verifying mail routes, or debugging domain settings, this tool streamlines DNS management.
