Subdomain Enumeration

the process of discovering and mapping all the subdomains associated with a particular domain. This information can be useful for security professionals in identifying potential attack surfaces and vulnerable areas within a target domain.

In subdomain enumeration, various tools are used to identify the subdomains of a domain by querying its domain name system (DNS) records. The DNS records reveal information about the subdomains and IP addresses associated with the target domain, including any subdomains that might have been missed during a regular port scan.

Subdomain enumeration is an important aspect of reconnaissance, as it can provide insight into the target's internal structure, identifying potential vulnerabilities and access points that might not be visible on the surface. This information can then be used in later stages of penetration testing or bug-hunting engagement to plan and execute attacks on the target.

It is important to conduct subdomain enumeration in a legal and ethical manner, and with the permission of the target domain's owner.
