As service providers and enterprises deploy new IP services and technologies such as voice over IP (VoIP), IP videoconferencing, wireless, cloud computing, and virtualization, their IP networks and traffic can quickly explode in size and complexity. Devices on the network have also proliferated - each requiring its own IP address. Management of IP address space and the corresponding Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) server configurations can quickly become overwhelming.

Traditional IP address management (IPAM) tools, such as spreadsheets, homegrown systems, and even early versions of IPAM software are becoming technically obsolete - no longer reliable or scalable in the current environment. Many network operators run both IPv4 and IPv6 networks, and new, more complex IPv6 networks call for more dynamic address management. Network operators now require a full-featured, automated IPAM solution to plan, track, and manage the IPv4 and IPv6 address space used in their networks.

Product Overview

Cisco Prime Network Registrar IP Address Manager (IPAM) is a scalable, high-performance and extensible solution that provides centralized visibility and control to effectively manage today’s increasingly dynamic and complex networks. The application can manage, monitor, alert and report on the entire IP space and DHCP and DNS services - all from a single intuitive web interface.

With the continual deployment of new IP services and technologies, the increasing number of connected users, and the explosive growth in connected devices, today's complex networks require a full-featured, automated IPAM solution. Without a next-generation, scalable IPAM system to plan, track, and manage the full lifecycle of IP address space and ease the transition to IPv6, service providers and enterprises risk operating inefficiencies, unnecessary costs, and delayed service activation.

Indeed, the introduction of IPv6 into network environments presents significant challenges and added complexity in the realm of DNS, DHCP, and IPAM (DDI). Because the migration to IPv6 will take many years, it is important to have DDI support for both IPv6 and IPv4. Network operators require a full-featured, automated IP address management solution that supports IPv4 and IPv6 to plan, track, and manage IP addresses and ease the transition to IPv6.

Cisco Prime Network Registrar IPAM meets these challenges by providing comprehensive, automated IP address management for simplified control of the IP address space for both IPv4 and IPv6 networks (see Figure 1).

Cisco Prime Network Registrar IPAM is an integral component of Cisco Prime Network Registrar. The complete Cisco Prime Network Registrar solution includes the following components and their respective services - all supporting both IPv4 and IPv6:

   A single DHCP server for device network access

   A single DNS server for IP address translation and service delivery

   A DNS caching server that supports DNS Security Extensions (DNSSEC) and is designed to prevent cache poisoning and other attacks

   A powerful, comprehensive IPAM system to automate and manage all IPv4 and IPv6 address requirements

Cisco Prime Network Registrar IPAM can be deployed as a standalone application or can be integrated with the DHCP and DNS server components of Cisco Prime Network Registrar. In addition, it cohesively supports Internet Systems Consortium (ISC DHCP and BIND 9 DNS) and Microsoft DHCP and DNS services. With this multivendor support on existing infrastructure, IT managers no longer have to maintain multiple management consoles or deal with complex command-line interfaces (CLIs).

  Users can plan and stage the following interrelated entities for immediate or future deployment to DHCP and DNS servers: IP block or subnet allocation, IP address assignment, IPv6 prefixes and links, addition of a new DHCP pool and associated parameters, or DNS domain, server configuration, or resource records.
  Discovery-to-database reconciliation and exception reporting help enable operators to view plan discrepancies and potential errors or rogue users.

Creation and management of IPv6 prefixes and links

Using IPv6 prefixes or links, operators can easily perform IPv6 address allocation, assignment, tracking, and search - for significant operational efficiencies compared to manual processes.

Definition of DHCPv6 options and client classes

Client classes may be used to associate classes of devices with policies and options. For instance, you can create a VOIP client class or a cable modem client class with a policy set to provide an address (out of a given scope or prefix) with associated options.


Creation and management of IPv4 and IPv6 client reservations

Cisco Prime Network Registrar IPAM allows users to easily select and assign an IP address or prefix.

User definability/flexibility and management of IP address space

Easy-to-use container architecture allows the user to define and manage topology, address space (including block allocations and subnets), device and block types, and associated attributes (through user-defined fields). This helps administrators to organize address space in a manner that best matches an organization's structure.

Address allocation: User-defined policies and automation

  IPAM allows users to allocate space in a hierarchical, logical manner in accordance with the topology as defined in their IP address plan.
  Automated allocation prevents requiring the operator to manually enter IP addresses, improving worker productivity and network uptime, decreasing costs, and allowing service providers and enterprises to scale seamlessly.
  Optimal "best fit" address allocation maximizes address utilization efficiency.
  Customization through multiple block types provides multiple address subspaces for various applications or IP types such as data, VOIP, higher quality of service (QoS), and more.
  Simplified address renumbering allows movement of address space where it is needed.

Automated and manual IP address and subnet reclaim

IPAM provides the ability to reclaim or free up IP addresses or entire subnets - a task that is crucial to assuring the IP inventory database is accurate.
