Organic Design procedure

Our .com domain host is namecheap.com and they provide a free dynamic DNS solution allowing simple HTTP query-string based method of updating a sub-domain. We just add a single entry to /etc/crontab which looks like this (replace SUB, DOMAIN and PASS with your specific settings):

*/10 * * * * nobody wget -q --spider "http://dynamicdns.park-your-domain.com/update?host=SUB&domain=DOMAIN&password=PASS"

The subdomain will automatically be created when the first request is made if it didn't previously exist. The password is shown in the namecheap.com admin site in the "DynamicDNS" section for the appropriate domain.
