in thread Cisco SNMP CDP Poll

In my case I have found that some devices return strange output, it is in case no mgmt IP is available in sh cdp nei detail (CSS11501), older IOS or different platform. 
DB<69> p $_[0]
DB<70> x $_[0]
0  "\c@\c@\c@\c@"

My dirty hack for that was just check for valid hex-like input 
          #if (substr($hex_ip,0,1) eq ""){
          if ($hex_ip !~ m/0x.*/){
          $ip = "0.0.0.0";
            }

    is there a way to modify this script so that it will cycle through a list of choices to use for comminuty string on each device it is polling? Sorry I have no experience at coding, but this script is EXACTLY what I need. I am doing a discovery, I have a list of possible community strings though so i am stuck.
