说明
fierce is a DNS reconnaissance tool that locates non-contiguous IP space and hostnames for a target. It performs zone transfers, subdomain brute forcing, and adjacent IP discovery. The tool attempts DNS zone transfers first, then falls back to dictionary-based subdomain enumeration. When hosts are found, it scans nearby IP addresses to discover additional systems. fierce is used in penetration testing for initial target enumeration and attack surface mapping.
