CERT SiLK IPset
CERT SiLK IPset is a distribution that contains a library and a set of command line tools for building and manipulating IPset files, which are binary files containing a set of IP addresses. SiLK IPset is designed for those who wish to use IPsets but who don't need the entire SiLK tool suite. It includes four command line tools:
- rwsetbuild reads (textual) IP addresses in canonical form or in CIDR notation from an input file or from the standard input and writes a binary IPset file.
- rwsetcat prints the contents of a binary IPset file as text.
- rwsetmember determines whether the IP address or CIDR block specified on the command line is contained in an IPset.
- rwsettool performs union, intersection, difference, and sampling functions on the input IPset files, generating a new IPset file.
