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.
