title: How to find my localtion public IP address?
body: <p>In my LAN I use a <code>192.168.0.0/24</code> IP address, and Regional carriers using the NAT tech let us can access Internet, so there is a public IP address.</p>
  <p>I can use ipip.net to check the public IP address I am using.
  but, this will open a web page, is there any other API I can use code to check?</p>
