A DNS scanner can help locate discontinuous IP spaces and host names based on specified domains.
Fierce is a semi-lightweight scanner that can help you locate discontinuous IP spaces and hostnames based on specified domains. In fact, this is the pioneer of nmap, OpenVAS, nikto, etc., because all of these require you to already know the IP space you are looking for. This will not take advantage of, nor will it scan the entire Internet indiscriminately. It is specifically used to locate possible targets inside and outside the company network. Because it mainly uses DNS, you will often find that a misconfigured network leaks internal address space. This is especially useful in targeted malware. Originally written by RSnake and others on http://ha.ckers.org/. This is just a conversion to Python 3 to simplify and update the code base.
