Takes a list of 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 supurfluous 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.
