title: How to access specific numbers of a ipv4 address?
body: <p>I have many ipv4 addresses with the fourth octet obfuscated with a 3 character string like <code>(###.###.###.xxx)</code> and i need to define each number between the dots.<br>
  For example <code>22.123.567.cjj</code> than <code>w=22</code>, <code>x=123</code> and <code>y=567</code>.<br>
  Sometimes the first octet has 3 numbers or (how you can see) 2 and sometimes just 1.  </p>
  
  <p>Can anyone help me ?</p>
