  <p>This above code is actually dumped in a file (say abc.txt) and it is a valid JSON format. I need to open the file and traverse to the "label" field.
  I need to write a code which should extract/print the "label" value only if it is a IP i.e something in format of 0.0.0.0 </p>
  
  <p>How to do so ?</p>
