It only updates when it has changed, or every 28 days if it hasn't so that dnydns.org doesn't drop you from their database for being idle. I only run it every five minutes to see if the address has changed. It might serve as a nice template for your script. The source is easy to understand. See http://ipcheck.sourceforge.net 2) dnydns.org is free as well I know nothing about zoneedit.com. Sorry!
