Frequently Asked Questions

Q: What is a DNS lookup?

A: A DNS lookup queries DNS servers to retrieve records for a domain, such as its IP address, mail servers, or text verification records.

Q: What DNS record type should I look up?

A: Use A records to find a domain's IP address, MX records to check mail servers, TXT records to verify SPF and DKIM, and CNAME records to check domain aliases.

Q: Why are my DNS records not updating?

A: DNS changes take 24-48 hours to propagate globally due to TTL (Time to Live) caching. Use this tool to check if your DNS changes have propagated yet.
