Edwin Groothuis ad0ad50784 net-mgmt/grepcidr: Filter IP addresses matching IPv4 CIDR/network specification
grepcidr can be used to filter a list of IP addresses against
    one or more Classless Inter-Domain Routing (CIDR) specifications,
    or arbitrary networks specified by an address range. As with
    grep, there are options to invert matching and load patterns
    from a file.  grepcidr is capable of comparing thousands or
    even millions of IPs to networks with little memory usage and
    in reasonable computation time.

    grepcidr has endless uses in network software, including: mail
    filtering and processing, network security, log analysis, and
    many custom applications.
