### Recommended Resources for DNS Lookups and Troubleshooting

#### Overview

Need help with DNS? When managing a website or domain, DNS tools can help you check records, diagnose issues, and speed up problem-solving. This guide introduces tools, some created by our team and others publicly available, that you can use to test and review your DNS settings.

#### Public Tools by Liquid Web and Nexcess

#### Using Whois

Whois is a powerful tool that helps you look up information about a domain name. With it, you can find out:

- Who the domain is registered to (or “rented” by)
- Which registrar manages the domain
- Contact details for the technical and administrative owners
- The domain’s nameservers
- DNSSEC (DNS Security Extensions) status
- When the domain is set to expire

This tool is especially helpful when you’re troubleshooting DNS or verifying ownership details.
