raggre
Aggregate IPv4 network addresses.
Since v0.5.0 raggre4 and raggre6 are combined into raggre.
This is a rust program. Dependencies: clap. Random IP generators
ruran4 and ruran6 require rand. libc is used to handle SIGPIPE.
By default IP addresses are accepted if /nn network specified is invalid; for example
1.4.5.6/16 is accepted and processed as 1.4.0.0/16; if you wish to ignore
them, use parameter --ignore-invalid, then such addresses are silently
ignored.
This program may or may not be suitable for your use case, feel free to read the code and make a pull request. https://github.com/Safari77/raggre46
