The value of 291 seems awfully high. Most of the ip's that I work with have 0, 1, or 2, sometimes more. They refer to the number of prefixes, "/nn", for point-to-point networks. The + sign means that it has been signed with an extra 32-bit integer, again, for point-to-point broadcast purposes. It may make more sense if we look at the whole bundle of methods. 

#!/usr/bin/perl -l

use strict;
use warnings;
use Net::IP qw/:PROC/;
use Data::Dumper::Concise;

my $netip = new Net::IP ('157.166.255.18') 
    or die (Net::IP::Error());
print Dumper( 
    "IP   : " . $netip->ip(),
    "Sho  : " . $netip->short(),
    "Bin  : " . $netip->binip(),
    "Int  : " . $netip->intip(),
    "Mask : " . $netip->mask(),
    "Last : " . $netip->last_ip(),
    "Len  : " . $netip->prefixlen(),
    "Size : " . $netip->size(),
    "Type : " . $netip->iptype(),
    "Rev  : " . $netip->reverse_ip(),
    "Pre  : " . $netip->is_prefix(),
);
    
print Dumper( $netip );
