Here is a way to parse the config file: 
while (<DATA>) {
   my ($prefix, $rest) = split;
   foreach my $env (split /;/, $rest) {
      my ($env_name, $machine) = split /:/, $env;
      print "$prefix $env_name $machine\n";
   }
}

Update: That 100, 101 and 106 look a little suspicious. If you meant to expand the number intervals as well, a little extra code is needed: 
while (<DATA>) {
   my ($prefix, $rest) = split;
   foreach my $env (split /;/, $rest) {
      my ($env_name, $machine) = split /:/, $env;
      if ($machine =~ /^(\D+)(\d+)-(\d+)$/) {
         my $root = $1;
         foreach $num ($2..$3) {
            print "$prefix $env_name $root$num\n";
         }
      }
      else {
         print "$prefix $env_name $machine\n";
      }
   }
}
