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 millions of devices and forms the basis of a DOCSIS cable modem provisioning system. For telecom service providers, Cisco Network Registrar is an integral part of service networks such as DSL and WiMAX as well as voice over IP (VoIP) and business services infrastructures.
Cisco Network Registrar includes a standards-compliant DNS server that offers an advanced feature set, 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).
A configuration wizard helps users navigate through different Cisco Network Registrar configuration steps. With the wizard, users can easily perform DHCP and DNS configuration by entering the parameters that are essential for the configuration. This is the basic configuration mode. The advanced configuration mode is still available for users with more in-depth experience of DNS and DHCP configuration.
Real-time server status dashboard
The dashboard provides an at-a-glance, real-time indicator of the server health, system metrics, alarms and alerts, and inventories of the Cisco Network Registrar server. The dashboard displays graphs for monitoring DHCP and DNS general information, throughput, and error data that can affect network operations. To measure address usage over time, the dashboard can collect DHCP utilization information for a time period and present graphs showing trends that are useful for capacity planning.
Improved search capability
Users can search for an IP address and retrieve the relevant information associated with the address. Users can find out the current state of the address, the scope to which it belongs, and the date and time the lease was granted. Users can start the search by entering the IP address or a MAC address that is associated with the IP address.
Carrier-class lease reservation performance
For users with needs for static IP address assignment, Cisco Network Registrar can handle up to 500,000 lease reservations. Because Cisco Network Registrar supports failover deployment, the enhanced lease reservation synchronizes the lease reservation between the main and the backup server to make sure that any update to the configuration will be populated between these servers. Modification to the reserved lease configuration can be done through the web UI, a command-line interface (CLI), and the Java Software Development Kit (SDK).
Dynamic lease notification
With dynamic lease notification, customers can have external systems notified whenever Cisco Network Registrar issues a lease. This feature is used in lawful intercept solutions and long-term storage of customer data for regulatory compliance and operational efficiency.
To help users through the installation procedure, the wizards provide assistance on each data point or wherever a decision is required. Default configuration is available to allow users to quickly install Cisco Network Registrar. The wizards summarize and present all the entered input to users, thus effectively giving users a chance to review the configuration values before proceeding with the installation.
Installation sanity check
Cisco Network Registrar helps ensure that the server has the required minimum memory and disk capacity before allowing the installation process to move forward. The checklist includes the appropriate operating system version, hardware dependencies, and required software components like Java. If the server does not meet all the items on the checklist, the installation will not proceed, thus avoiding potential problems that might arise due to inadequate system resources.
Cisco Network Registrar creates a log file that captures all the user input, responses, and error information generated during the installation. If users encounter any problem during the installation, they can diagnose the problem by reviewing the input and output information, which plays back the full installation activities.
