Why Use DNS & Domain Tools?

DNS (Domain Name System) is the backbone of the internet, translating human-readable domain names into IP addresses. Our free DNS tools help you troubleshoot domain configuration issues, verify email setup (MX, SPF, DKIM records), check domain ownership, and ensure DNS changes have propagated correctly. Essential for webmasters, DevOps engineers, and anyone managing domains.

Domain Troubleshooting

Diagnose why your website isn't loading or email isn't working. Query DNS records to find configuration issues and mismatched settings.

Email Setup Verification

Verify MX records point to your email provider. Check SPF and DKIM TXT records to prevent your emails from going to spam.

Domain Research

Check domain ownership and registration history with WHOIS. Find out when a domain expires or who to contact for domain disputes.

Migration Verification

Confirm DNS changes have propagated after migrating to a new host. Verify nameservers, A records, and CNAME configurations.

Frequently Asked Questions

What is DNS and what are DNS records?
DNS (Domain Name System) translates domain names to IP addresses. Common DNS record types include: A records (IPv4 addresses), AAAA records (IPv6 addresses), MX records (mail servers), TXT records (verification and SPF/DKIM), NS records (nameservers), CNAME records (aliases). DNS lookup tools help you query and troubleshoot these records.
How do I check DNS records for a domain?
Use bugX's DNS Lookup tool: 1) Enter the domain name (e.g., example.com), 2) Select the record types you want to query (A, MX, TXT, NS, etc.), 3) Click Lookup to see all records. This helps verify DNS configuration, troubleshoot email delivery issues, and check if DNS changes have propagated.
What is WHOIS and what information does it show?
WHOIS is a protocol for querying domain registration information. It shows: registrar name, registration and expiration dates, nameservers, and sometimes registrant contact details (if not privacy-protected). Use WHOIS lookup to check domain ownership, expiration dates, or find contact information for domain disputes.
How long does DNS propagation take?
DNS propagation typically takes 24-48 hours globally, but can be faster. Factors affecting propagation: TTL (Time To Live) values on records, ISP caching policies, and geographic location. To speed up propagation, lower your TTL before making changes. Use our DNS lookup tool from different locations to check propagation status.
Why is my email not working after changing DNS?
Email issues after DNS changes are usually due to: 1) Incorrect MX records - verify they point to your email provider, 2) Missing or incorrect SPF/DKIM TXT records - check spam authentication, 3) DNS propagation delay - wait 24-48 hours, 4) TTL caching - old records may still be cached. Use our DNS Lookup tool to verify all email-related records are correct.
