Hi all!

Ive got a problem performing IP address operations using Net::IP.

Here is what i need: I have to translate an IP address (for example, 10.0.1.3) into an integer value (for example, 167772419), and translate an integer value to an ip (167772419 to 10.0.1.3). I did:

use Net::IP qw(:PROC);

my $ipaddr = '10.0.1.3';
my $ip = new Net::IP($ipaddr) or die (Net::IP::Error());
my $int = $ip->intip();

print "Integer value of IP $ipaddr: $int\n";

And it prints:
Integer value of IP 10.0.1.3: 167772419

Which is correct. But the reverse operation:

use Net::IP qw(:PROC);
                                                                      
+                                                                     
+      
my $intaddr = 167772419;
my $binaddr;
eval{
     $binaddr = ip_inttobin($intaddr);
};
die "Error: $@" if($@);

!defined($binaddr) and print "Binary not defined\n";
print "Binary value of integer $intaddr: $binaddr\n";

Prints:

Binary not defined
Binary value of integer 167772419:

Thus, i dont know how to transform an integer into a binary, and a binary into an ip, which is the only way i currently know.

Any idea on how to deal with this?
Thank you
