As Krambambuli noted, the @sorted1 code is correct and the @sorted isn't. In the wrong one, you're applying split to an array reference.

Seeing as how you are sorting ip adresses, you could simplify this sort routine using Socket's function inet_aton. 

#!/usr/bin/perl
use strict;
use warnings;
use Socket;
use Data::Dumper;

my @data = map{[split]} <DATA>;
print Dumper \@data;

my @sorted = map{$_->[0]}
            sort {$a->[1] cmp $b->[1]}
             map { [$_, inet_aton($_->[1]) ]} @data; 
print Dumper \@sorted;

__DATA__
alpha 2.23.14.71
beta 10.23.14.71
gamma 25.26.1.6
delta 1.2.3.4
epsilon 10.24.14.71

Socket is included with perl 5.8.8 at least, and likely for earlier versions of perl.
