Net::IP solutions:
# for just DottedQuadToLong():
use Net::IP;
print Net::IP->new("24.72.30.83")->intip;
# for both directions:
use Net::IP qw/:PROC/;
print ip_bintoint(ip_iptobin("24.72.30.83",4));
print ip_bintoip(ip_inttobin("407379539",4),4);
couple code comments:
- Personnally i'd write foreach (@quads) { $_ = hex } w/map: return join '.', map {hex} @quads;
- in DottedQuadToLong, the split is just extra work -- just capture each piece (don't need the substitution, either)
sub DottedQuadToLong {
my $ip_str = shift;
return 0 unless $ip_str =~ /^\s*(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(
+\d{1,3})\s*$/;
my $ip = 0;
foreach my $quad ($1,$2,$3,$4){
return 0 if ($quad > 255);
$ip = $ip * 256 + $quad;
}
return $ip;
}
