Good morning:

I'd start by changing the main loop, first and last line:
To:
Code:
while read tIP pIP
...
done</home/lotus/bin/cmd/$iptable_fil

So it now reads the the first value for 't'elnet-ip, and the second value for 'p'ing-ip.

Why are you reading the whole line in 2 loops, in- and outside?
Makes it much more complex and slower thant it would be.

Are you sure you even need the 'telnet' ips?
You set the mainnode, bu never use it (or i overseen it).


From one of my scripts:
Code:
ping -c1 $URL | grep -e trans -e ms

You could chagne to like:
Code:
ping -c1 $pIP | grep -e trans -e ms && \
     echo "$pIP  : $data" >> result_ping.log || \
     echo "$pIP  : 100% packet loss" >> result_ping.log

Basicly, the 2 examples should be enough.
-- though, the $data is now unset (empty).

For a new one, you writing quite complex scripts Smilie
Anyway, just writing the basics, try (untested):
Code:
while read tIP pIP
    ping6 -c1 $pIP | grep -e trans -e ms && \
         echo "$pIP  : Found" >> result_ping.log || \
         echo "$pIP  : 100% packet loss" >> result_ping.log
done</home/lotus/bin/cmd/$iptable_fil
