DZone Snippets: dyndns code http://snippets.dzone.com/posts Mon, 08 Sep 2008 05:52:32 GMT DZone Snippets: dyndns code Finding your WAN IP address http://snippets.dzone.com/posts/show/5346 My server sits behind a NAT router, so finding out my public IP address is a non-trivial task. I can use curl to poll checkip.dyndns.org for my current address: <br /><code> <br />curl -s checkip.dyndns.org <br /></code> <br />The current IP check returns the information in this format: <html><head><title>Current IP Check</title></head><body>Current IP Address: 216.239.39.99</body></html> <br /> <br />Using cut, I can extract just the information that I need: <br /><code> <br />curl -s checkip.dyndns.org|cut -d ":" -f2|cut -d "<" -f1 <br /></code> <br />That produces something a bit more readable: 216.239.39.99 <br /> <br />------------------------- <br />This article snippet was copied from <a href="http://www.linux.com/articles/52552">My sysadmin toolbox</a> [linux.com] while I was googling for 'apt-cache search dyndns'.
