The harder way:

Decimal: 1089055123 Hex (dashes inserted at octals): 40-E9-A9-93 Decimal (of each octet): 64-233-169-147 IP Address: 64.233.169.147

The Python way

...

import socket, struct socket.inet_ntoa(struct.pack('>l', 1089055123)) '64.233.169.147'

The Perl way:

sub ntoa { my $one = shift; my $four = $one & 0xff; $one >>= 8; my $three = $one & 0xff; $one >>= 8; my $two = $one & 0xff; $one >>= 8; return "$one.$two.$three.$four"; }

#or in one line, like ipcalc does: sub ntoa_in_one_line { join(".", unpack("CCCC", pack("N", $_[0]))); }

print ntoa(1089055123) . "\n"; print ntoa_in_one_line(1089055123) . "\n";

The PHP way: function convertIntegerToIpv4($integer) { $max_value = pow(2,32); //4,294,967,296 $bug_fix = 0; settype($integer, float); if($integer > 2147483647) $bug_fix = 16777216; if(is_numeric($integer)) { if ($integer >= $max_value || $integer < 0) { return ('Not a valid IPv4 integer'); } $ip = (sprintf("%u.%u.%u.%u", $integer / 16777216, (($integer % 16777216) + $bug_fix) / 65536, (($integer % 65536) + $bug_fix / 256) / 256, ($integer % 256) + $bug_fix / 256 / 256 ) ); return($ip); } else { return(''); } } *************************************************************************************** The information contained in this message, including attachments, may contain privileged or confidential information that is intended to be delivered only to the person identified above.
