Backtrack 4: Information Gathering: DNS: Fierce – locate non-contiguous IP space and hostnames against specified domains

These include – trying to dump the SOA records, do a zone transfer, searching for commonly used domain names with a dictionary attack, adjacency scan and a few more. Fierce is meant specifically to locate likely targets both inside and outside a corporate network. Only those targets are listed (unless the -nopattern switch is used). No exploitation is performed (unless you do something intentionally malicious with the -connect switch). Fierce is a reconnaissance tool.
