I have a very simple perl script to convert a set of numbers into hex (converting dotted quad to hex). Here is the script: 
#!/usr/bin/perl
$octet1 = 10;
$octet2 = 34;
$octet3 = 2;
$octet4 = 252;

$hex1 = sprintf("%x", $octet1);
$hex2 = sprintf("%x", $octet2);
$hex3 = sprintf("%x", $octet3);
$hex4 = sprintf("%x", $octet4);

print "$hex1\n";
print "$hex2\n";
print "$hex3\n";
print "$hex4\n";

My output is this: 
a
22
2
fc

How would you left justify/pad the values so that the desired output would be this? 
0a
22
02
fc

This is an attempt to convert a dotted quad ip address from 10.34.2.252 to a hex value of 0a2202fc. If someone has a better suggestion on how to accomplish this, I'm all ears.
