## SYNOPSIS

zblacklist [ -b <blacklist> ] [ -w <whitelist> ] [ OPTIONS... ]

## DESCRIPTION

*ZBlacklist* is a network tool for limiting and deduplicating a list of

## OPTIONS

### BASIC OPTIONS ###

   * `-b`, `--blacklist-file=path`:
     File of subnets to exclude, in CIDR notation, one-per line. It is
     recommended you use this to exclude RFC 1918 addresses, multicast, IANA
     reserved space, and other IANA special-purpose addresses. An example
     blacklist file **blacklist.conf** for this purpose.

  * `-w`, `--whitelist-file=name`:
    File of subnets to include, in CIDR notation, one-per line. All other
    subnets will be excluded.

  * `-l`, `--log-file=name`:
    File to log to.

  * `-v`, `--verbosity`:
    Level of log detail (0-5, default=3)

  * `--no-duplicate-checking`:
    Don't deduplicate input addresses. Default is false.

  * `--ignore-blacklist-errors`:
    Ignore invalid entries in the blacklist. Default is false.
