Cisco Network Registrar Overview

Cisco Network Registrar provides scalable, reliable, and integrated Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), and IP Address Management (IPAM) services (DDI) for both IPv4 and IPv6.

The solution offers

   Proven scalability: DHCP services for more than 50 million devices in a single customer deployment.

   Reliability: DHCP safe failover, support for high availability DNS, and unsurpassed avalanche prevention to reduce downtime after network outages.

   Single platform for consolidated IP address management: Full IPv6 support helps automate and manage the transition from IPv4 to IPv6 by using dual-stack deployment on a single server. The full-featured DHCPv6 server provides support for address assignment, prefix delegation, and stateless and stateful configuration for full IPv6 address management.

   High-performance provisioning of IP addresses for all services including mobile, cloud, and video.


Cisco Network offers comprehensive DNS, DHCP, and IPAM services with the following key benefits:

   Fast: Able to assign more than 47,000 leases per second on a Cisco B-Series Unified Computing System (UCS) platform (and 14,000 leases per second on a non-Cisco hardware platform).

   Easy to manage: Network administrators can control and monitor DNS and DHCP servers from a centralized location to synchronize information, reduce outages, and improve efficiency. These IPAM capabilities help reduce operational errors and costs.

   Low risk and reduced startup costs: Able to be deployed in a virtualized environment.

New in Release 7.2

   New cloud support: New multitenant capabilities provide the ability to manage multiple customer DHCP services from a single instance and provide secure, self-service access through the web.

   Better usability: Includes simplified query and dashboard capabilities and expanded authentication and authorization support. In addition, a new improved web UI and new platform support provide improved navigation and greater customer choice.

   New DHCP server functionality: Expanded client reservation functionality and support for DHCP bulk lease query in Version 6 are now available.

   New virtualized appliance availability: Option to deploy Cisco Network Registrar as a preconfigured virtual appliance - simplifying installation, lowering deployment risks, and reducing startup costs.

   Expanded management support over IPv6: Command-line interface (CLI) and Cisco Network Registrar Software Development Kit (SDK) connections are now provided for IPv6.

Enhancements and New Features



New Cloud Support

Multitenant management

  Provides the ability to segment data stored on both regional and local clusters by tenant. 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.
  Creates a central management point for customers' configurations and network data.
  Within a local cluster, address pools and domain names to a given tenant are separated, allowing multiple tenant environments to coexist on a single instance of Cisco Network Registrar.
  Allows delivery of secure DNS and DHCP services to multiple customers from a single instance.
  Helps users reduce operational costs through IPAM implemented at the regional cluster.
  With IPAM, 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.

Better Usability

IPv4 and IPv6 lease history

  Lease history for DHCP for IPv6 (DHCPv6) in addition to DHCP for IPv4 (DHCPv4).
  Historical views regarding DHCPv6 services include data by lease, client, date, length of lease, and so on.
  Helps enable proactive analysis of service consumption and trends.

Improved UI lease history query

  Searching of lease history is now possible both at regional and local clusters.
  Improvements include:
   Web UI enhancements
   An “iphist” tool for local and regional clusters
  Allows for a better user experience and greater query access and customization.

RADIUS authentication support for management

  Extends Cisco Network Registrar administrator authentication to RADIUS (first external authentication).
  Allows network administrators to define a pool of authorized users along with attribute information that specifies the roles for which each user is authorized.
  Allows network administrators to use RADIUS to manage users and groups centrally. Previously, users, groups, and permissions were all configured locally on the Cisco Network Registrar server.

New platform support

  Platform support includes Windows Server 2008 R2, Solaris 10, and Red Hat ES 5.
  New certification to run on Solaris 10 logical domains (LDOMs), VMware ESX 4.x (for Red Hat ES 5 and Windows 2008 Server R2), and Cisco Unified Computing System (UCS).
  Greater customer choice regarding operating systems.
  The ability to be deployed in a virtualized VMware environment allows for lower total cost of ownership (TCO), ease of deployment (seven minutes versus hours previously), and greater flexibility in migration and backup.

New improved web UI look and feel

  New look and feel that is visually appealing.
  Improves product navigation with an improved menu system.

New DHCP Server Functionality

Client reservations

  Client reservations for IPv4 and IPv6 addresses as well as IPv6 prefix delegation.
  Reservations can be stored internally or externally - either in Lightweight Directory Access Protocol (LDAP) or supplied through the DHCP server’s extension interface from other external sources.
  Eliminates the need to synchronize the customer’s database with the Cisco Network Registrar lease reservations database.
   Provides for a much more dynamic and scalable reservation-based service.

Bulk lease query in Version 6

  Support for DHCPv6 bulk lease query for the following query types:
   Query by IPv6 address
   Query by client ID
   Query by relay ID
   Query by link address
   Query by remote ID
  Minimizes network traffic and represents a more efficient way of passing large amounts of data back and forth.
  This feature is necessary to work with cable modem termination system (CMTS) units.

New Virtualized Appliance Availability

Virtual appliance support

  New VMware virtual appliance option - preinstalled on a Linux operating system.
  Includes all software necessary to operate Cisco Network Registrar and will run on any VMware ESXi 4.1-capable server.
  Lower TCO and greater ease of deployment.

Expanded Management Support over IPv6

Full support for management of Cisco Network Registrar over IPv6.

  IPv6 support for CLI and Cisco Network Registrar SDK connections (in addition to the Web UI).
  Administrators can now connect to regional and local clusters using the web UI, the SDK, and the CLI over IPv6 as well as IPv4.
