I don't know what a DNS thingy is Smilie
Maybe read the file into a while-loop like
Code:
while read IP; do
   ping $IP #with some options
   if [ $? != 0 ]; then
      echo "$(date) --- IP $IP not responding." >> $YOURLOGFILE # you have to declare that somewhere up there
   else
      echo $IP >> the.list.that.will.checked.further.on
   fi
done < file.with.a.list.of.ip.addresses.to.ping

4. Question arises - what's the need for successful IPs..!?
What is a successful IP? If that is what I guess, you should get it from my former post where you test $?.

Can't believe that Smilie

3. As of now, the bit I'm struggling w/ is:
using 'grep' to fetch the IP from the same line where I'm grepping - "unreachable host"..
You don't need to grep it, as testing the return code of ping you know which IP you are currently processing and can just redirect it to your further to be processed list; see up there after the else.
