GnuDIP is a service desiged for an ISP to give its customers a static DNS name without having to give them their own IP address. For those who are familiar with ml.org this is a simple replacement. GnuDIP has 2 main parts on the server side.
1, the multi-threaded server that listens on a port accepting connections from client applications and updates their hostname, and
2 the web cgi that is used as the administration tool and as the users tool to manage their own account.
Using the web cgi a user can set their desired homepage in their settings and then set the special URL as the default page for their browser so now every time they open their browser their hostname will be automatically be updated without having to run any other sort of client application and then they would be redirected to the URL they set in their GnuDIP settings.
