Split the network and netmask into separate terms and sort on netmask within network.

knoppix@Microknoppix:~$ perl -MSocket -Mstrict -wE '
my @networks = qw{
   10.182.8.0/26
   10.182.8.0/21
   10.182.8.64/26
   10.182.8.128/26
   10.182.8.192/26
   };

say for
   map  { $_->[ 0 ] }
   sort { $a->[ 1 ] cmp $b->[ 1 ] || $a->[ 2 ] <=> $b->[ 2 ] }
   map  { my( $network, $netmask ) = split m{/};
          [ $_, inet_aton( $network ), $netmask ];
        }
   @networks;'
10.182.8.0/21
10.182.8.0/26
10.182.8.64/26
10.182.8.128/26
10.182.8.192/26

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
