Subdomain Checker

Discover all the active subdomains of any domain name, instantly and for free.

What Is a Subdomain Checker?

A subdomain is an extension of a main domain name, such as blog.example.com or mail.example.com, used to organize a website into separate sections without registering a brand new domain. Our subdomain checker scans a domain against a list of the most common subdomain prefixes (blog, shop, mail, api, cpanel, webmail, and more) and reports which ones are live, along with the IP address each one resolves to.

This is useful for website owners auditing their own domain's footprint, developers mapping out a client's infrastructure before a migration, and security-conscious teams checking for forgotten or unauthorized subdomains that could be a security risk.
