I think what's happening is that the value of your hash is being 
reassigned at each point through your while loop.  Does this work 
better for you:

my %addresses;
while(<>) {
[...]
	$addresses{$bigaddr} = $_;
}



But I might be totally out of touch with what you're trying to do, in 
which case I apologize.
