%description
The grepcidr3 utility can be used to filter a list of IP addresses against
one or more Classless Inter-Domain Routing (CIDR) specifications, or also
arbitrary networks specified by an address range. As with grep, there are
options to invert matching and load patterns from a file. It is capable of
comparing thousands or even millions of IPs to networks with little memory
usage and in reasonable computation time.
