This is simply a\nconversion to Python 3 to simplify and modernize the codebase.\n\nThe original description was very apt, so I\u0027ll include it here:\n\n\u003e Fierce is a semi-lightweight scanner that helps locate non-contiguous\n\u003e IP space and hostnames against specified domains. It\u0027s really meant\n\u003e as a pre-cursor to nmap, unicornscan, nessus, nikto, etc, since all \n\u003e of those require that you already know what IP space you are looking \n\u003e for. This does not perform exploitation and does not scan the whole \n",
