+addresses with several dynamic DNS service providers, such as
+@uref{https://www.dyndns.com/account/login.html,DynDNS.com}.
+
+This makes it possible to use a fixed hostname (such as myhost.dyndns.org) to
+access a machine with a dynamic IP address.
+
+The client supports both dynamic and (near) static services, as well as MX
+record and alternative name management.  It caches the address, and only
+attempts the update when it has changed.")
