domain-sift domain-sift is a Perl script that extracts unique domains from at least one provided file and prints them to standard output in a given format. If no file is provided, domain-sift reads from standard input instead. One use of this utility is to extract domains from blocklists that contain known malicious or otherwise undesirable domains, and then format them in such a way that those domains can be blocked by a DNS resolver.
