grepcidr3 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. grepcidr3 is capable
|
|
of comparing thousands or even millions of IPs to networks with little
|
|
memory usage and in reasonable computation time.
|
|
|
|
grepcidr3 has endless uses in network software, including: mail filtering
|
|
and processing, network security, log analysis, and many custom applications.
