Net-CIDR-Overlap
A utility module for helping make sure a list of CIDRs don't overlap.
my $nco=Net::CIDR::Overlap->new;
# add some subnets
eval{
$nco->add( '127.0.0.0/24' );
$nco->add( '192.168.42.0/24' );
$nco->add( '10.10.0.0/16' );
}
if ( $@ ){
warn( $@ );
}
# this will fail as they have already been added
eval{
$nco->add( '127.0.0.0/25' );
$nco->add( '10.10.10/24' );
}
if ( $@ ){
warn( $@ );
}
# this will fail this is not a valid CIDR
eval{
$nco->add( 'foo' );
}
if ( $@ ){
warn( $@ );
}
# print the subnets we added with out issue
my $list=$nco->list;
foreach my $cidr ( @${ $list } ){
print $cidr."\n";
}
