The Wikipedia article is defective, but still useful.
http://en.wikipedia.org/wiki/Dynamic_DNSThe term is used to describe two different concepts. At the administration levels of the Internet, "dynamic DNS updating" refers to systems that are used to update traditional DNS records without manual editing. These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security.
Another kind of dynamic DNS permits lightweight and immediate updates to its local database, often using a web-based mechanism. It is used to resolve a well-known domain name to an IP address that may change frequently. It provides a persistent addressing method for devices that change their location or configuration.
