IP communications between service providers today are starting to evolve to support services other than General Packet Radio Service (GPRS) roaming. These new services rely upon Domain Name System (DNS) for inter-Public Land Mobile Network Multimedia Messaging Service (PLMN MMS) delivery and IP Multimedia Subsystem (IMS) interworking. Therefore, it is of utmost importance for service providers to choose the most resilient and reliable DNS solution to ensure that their customers experience seamless roaming and uninterrupted internet connectivity.
This white paper is intended to provide guidelines and technical information for those who need to set up or maintain DNS servers for inter-service-provider mobile services with Cisco Prime™ Network Registrar. With Cisco Prime Network Registrar DNS, service providers can satisfy client roaming needs both today and tomorrow by using the product’s built-in features, including but not limited to DNS High Availability, DNS Views, and VoLTE ENUM (E.164 Number Mapping), with a single DNS product architecture.
