About the DNS Lookup Tool
The DNS lookup tool queries a domain's DNS records so you can see how it is configured across the internet. It retrieves records such as A, AAAA, MX, TXT, NS, and CNAME, giving you a fast window into a domain's hosting, mail, and verification setup.
DNS is the backbone that maps domains to servers and defines how email and services route. Checking these records is essential for diagnosing connectivity problems, verifying email configuration, or investigating a suspicious domain.
Enter a domain to get an instant, private DNS report. Use it to troubleshoot your own setup or to research an unfamiliar domain.
Frequently asked questions
What is a DNS record?
A DNS record is an entry that tells the internet how to handle a domain, such as which server hosts the website (A record) or which servers receive its email (MX record).
What is a TXT record used for?
TXT records hold text used for verification and policy, including SPF and DMARC email-authentication settings and domain-ownership verification for various services.
Why would I do a DNS lookup?
To diagnose why a site or email is not working, to verify records you have set up are live, or to investigate the configuration of a domain you do not control.
