I have a domain via Namecheap. They support dynamic dns updates. I'd like to use my airport extreme (firmware 7.6.1) to do the DNS updates, anyone know how to accomplish this?
Here's the info about namecheap's dynamic dns. http://www.namecheap.com/support/knowledgebase/category.aspx/11/dynamic-dns
For what it's worth, I am willing to pay the $30 a year to use DynDNS instead, if I could get instructions for setting up the Airport Extreme.
