Yes. The 'DynDNS' Tim is looking for is the modification (and then
distribution) of the zone file based on dynamic IP address assignment to
the owner of the domain [ie ppp]. Monolith does this with a HTTP server
running a CGI form that has an account name, password and new IP. the
DynDNS client then simply pulls the IP from the interface and sends a HTTP
POST request to the server, it updates the zone file and then hups bind
(8) which invokes RFC 2136/1996 to update every secondary and presto, you
have a static hostname for a dynamic IP.
