I got half way through this before Jeff replied with a smarter answer.  But
here's a perl script to decode them for you if you prefer that:

#!/usr/bin/perl
# Call this script like this: "./test.pl 2130706433"
# And never mind the extra period at the end of the output
# And forgive my perl style please.

use strict;
use POSIX;

my $tmp;
my $ip = shift;
print "$ip: ";
for (3,2,1,0) {
        $tmp = $ip/(256**$_);
        print floor($tmp).".";
        $ip -= (floor($tmp)*(256**$_));
}
print "\n";
