An internet service provider or network owner can use the service sign-on method in a broadband IP internetworking infrastructure for user authentication to permit access of an access device to use network service enabled by the infrastructure and subsequent access records keeping. The access device is configured for dynamic host configuration protocol (DHCP) and incorporates software supporting Java applets. The sign-on method includes storing user related information in a provided database, answering DHCP packets, using a provided DHCP server, from the access device via an existing internetworking router in the infrastructure to establish communication of the access device via the router with an SSO web server, and serving a sign on form from the SSO web server to the access device to commence a pre-sign-on state for user authentication. A Java applet is provided from the SSO server to the access device to maintain a session representing that access to the network service is provided or to automate DCHP IP address lease renewal. The web server controls assignment of IP address to the access device and activates a per user access and service control policy on the router. Domain name server queries for the access device are answered by the domain name server (DNS) via the router for permitting access of the access device to the network service and records relating to the access are monitored and received for later accounting purposes
