I guess your problem is, that you build an anonymous array in your hash. When you want to get back the values from that array, you must do the following:

$player_info{$ipaddr} = [$nickname, $userid, $player_req];

for $key ( keys $player_info) {
  print @{$player_info{$key}}
}

or just fill the hash in an other way:

push @{$player_info{$ipaddr}} , ($nickname,$userid,$player_req);

print ${$player_info{$ipaddr}}[0]; ## gives the nickname ...

Remember you have a reference as a hash value, so you must deref it with adding a ${...}[index] or a @{...} to get access to the values of the array inside your hash.
Hope this helps.
