Product Overview
Cisco® Network Registrar® is an IP address management application that delivers IP address management (IPAM) features to ease the task of administering Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) services. For enterprise customers, Cisco Network Registrar offers a user-friendly GUI coupled with a built-in, granular administrative role capability to help users focus on running their business rather than dedicating the time to managing their DNS and DHCP services. For cable providers, Cisco Network Registrar provides scalable DNS and DHCP services for hundreds of thousands of devices and forms the basis of a DOCSIS® cable modem provisioning system. For telecom service providers, Cisco Network Registrar continues to play an important role in service activation for data, voice, and video over IP and mobile services.
Cisco Network Registrar includes a standards-compliant DNS server that offers the most advanced feature set in the industry, with support for incremental zone transfers, dynamic updates, and notifications. To secure DNS services, Cisco Network Registrar supports transactional signature (TSIG) to authenticate DNS zone transfer and update requests. Cisco Network Registrar DHCP server offers DHCP safe failover with redundant DHCP servers, dynamic DNS updates, and DOCSIS cable modems and integration with directory services using Lightweight Directory Access Protocol Version 3 (LDAPv3). Moreover, tight integration with Cisco IOS® devices further elevates the value of this Cisco powered network solution.
The scalable deployment architecture of Cisco Network Registrar consists of several local clusters and one regional cluster. The local cluster is deployed in the network to handle DNS and DHCP services. The regional cluster is usually deployed at the data center or the network operations center (NOC) for central management of the local clusters.
The regional cluster implements many IPAM features to help users reduce operational cost. With IPAM, Cisco Network Registrar administrators can control and monitor DNS and DHCP servers from a centralized location. This capability eliminates many manual, repetitive, and error-prone tasks in configuring the local servers deployed in the network and allows for a single point of data aggregation and delegation.
Address space management simplifies the task of managing address blocks and can be exercised from the regional cluster. An address block can contain static or dynamic addresses and can have any number of child address blocks culminating in one or more subnets. An administrator can break an address block into small units and push the smaller blocks to a local cluster. Similarly, the administrator can also roll up address blocks in the local cluster under their parent to provide a unified view of the address space. Instead of traversing every single local cluster to gather subnet utilization and lease history information, Cisco Network Registrar administrators can achieve the same result from the regional cluster and thus make the task of collecting usage data simple and virtually effortless. Without an automated solution, the complexity of managing address blocks can be high, and the task can be tedious and time consuming.
The regional cluster manages and monitors the local clusters through its cluster management capability. Cluster management allows central management of address spaces and global protocol server configuration, such as policies, client classes, and scope templates. Using the Web UI, the administrator at the regional cluster can add and manage a list of Cisco Network Registrar local clusters and their credentials. With this capability, Cisco Network Registrar administrators can create and manage a list of Cisco Network Registrar local clusters using the Web UI on the regional cluster. To further ease the administration task, administrators can centrally manage the local clusters, such as creating, pulling, and pushing VPNs, DHCP client classes, scope templates, and policies; managing failover pairs; and handling zone distribution. Through the Web UI, Cisco Network Registrar administrators can also pull subnet utilization and IP lease history data from the local clusters.
The enhanced interface helps ease the task of name and address administration and provides task-oriented Web pages for DNS and DHCP configuration. There are two configuration modes: basic and advanced. The basic mode targets initial Cisco Network Registrar setup and configuration. Instead of presenting a list of fields for the user to enter, the new user interface organizes data entry based on the tasks that are being carried out. Furthermore, to help users complete a configuration task, Cisco Network Registrar supports wizards that help users navigate through the configuration steps. Cisco Network Registrar also offers a dashboard that displays the real-time status of the DHCP and DNS servers. With the status dashboard, users can quickly glance at the Cisco Network Registrar console to see selective DHCP and DNS statistics, which can be represented in the graph of their choice. The data can act as alerts for situations that can become critical to the user's network operation and give users the opportunity to investigate and isolate the cause of the issue. To mitigate IP address scarcity and facilitate deployment of new revenue-generating services, Cisco Network Registrar offers support for DHCPv6 and DNSv6. This capability helps cable multiple Service operators (MSOs) roll out services that support the DOCSIS 3.0 specification for which IPv6 is required.
