# The net/aggregate port

## aggregate-1.6p1 – optimise a list of route prefixes

## Description

    Takes a list of IPv4 prefixes in conventional format on stdin, and performs
    two optimisations to attempt to reduce the length of the prefix list.

    The first optimisation is to remove any supplied prefixes which are
    superfluous because they are already included in another supplied prefix.
    For example, 203.97.2.0/24 would be removed if 203.97.0.0/17 was also
    supplied.

    The second optimisation identifies adjacent prefixes that can be combined
    under a single, shorter-length prefix. For example, 203.97.2.0/24 and
    203.97.3.0/24 can be combined into the single prefix 203.97.2.0/23.

    See the "aggregate6" package for an alternative tool that supports both
    IPv4 and IPv6.
