Abstract
A mobile communications network includes a packet service node capable of establishing a session with a mobile station. A network address (e.g., an Internet Protocol or IP address) of a domain name system (DNS) server is communicated to the mobile station using one of several types of messages. A first type of message includes an Internet Protocol Control Protocol (IPCP) message. A second type of message includes a Mobile Internet Protocol Registration Reply Message. The packet service node receives the network address of the DNS server from an authentication server, such as a RADIUS (Remote Authentication Dial In User System Service) server or a Mobile IP Authentication, Authorization, and Accounting (AAA) server.
