running noip from rc.local

I have downloaded and installed the linux client from no-ip.com. It compiled successfully, and now I am to the point of trying to get it to run automatically from boot. The instructions at http://www.no-ip.com/tips.php/id/13 say to place /usr/local/bin/noip2 in rc.local and reboot. At that point, it is supposed to run. So far, that is not happening. I have tried all the troubleshooting steps I could find, including 1. rc.local is executable 2. adding & to the command line in rc.local 3. running rc.local directly after I log in to make sure it works - it does is there some other step I need, such as do I have to do something with init.d?
