Everything dragonchild said holds true, let me append my .02 cents. This is how I would rewrite your script without altering too much. 
#!/usr/bin/perl -w
# IP ranger

use strict;

my ($stip,$edip,$count,@openip);

open(IPFILE,"<iplist.txt") # open readonly
    || die "Could not open iplist.txt:$! \n";

while (<IPFILE>) {
    
    chomp; 
    
    ($stip,$edip) = split(/:/,$_,2); # split(/:/);

    print "$stip\n";
    print "$edip\n";

    @openip = split(/\./,$stip); 
    $count = @openip;

    print "$count\n"; 

    # you can avoid the creation of the $count
    # variable and use the following statement               
    # print scalar(@openip), "\n";
                

#    for ($i = 0; $i <= 4; $i++) {
#        print "@srtip\n";
#    };
};

close(IPFILE);

Update: semi-colon after open() was a poorly over looked error... fixed
