In your code, you appear to have an "s" in the wrong place: 
foreach my $ip (@ips) 
{
    $record[7]=$ip;
    $csv->print ($ips, \@record); #Error probably here (ips -> ip)
}

probably what you need is: $csv->print ($ip, \@record);.

If you were using use strict; use warnings; This should throw a compile error because the scalar $ips is not defined.

One thing to consider is avoiding variables that differ by just a single letter (ips vs ip). It is very easy to make a typing mistake and get confusing results. Also be aware that in Perl, a symbol like "ips" can be both an array variable @ips and a different scalar variable like $ips at the same time. Not everything that is possible is wise. Just for consideration, assuming you keep @ips as is: 

foreach my $cur_ip (@ips) #or perhaps $this_ip or other name?
{
    $record[7]=$cur_ip;
    $csv->print ($cur_ip, \@record); 
}

Of course I have no context, but probably I would wind up changing @ips to something else: @local_ips, @network_ips, some name describing what kind of ips these are and keeping the simple $ip for the loop iterator name.
