The number of IP addresses and IP devices continues to increase dramatically,<br />
as does network size and complexity<br />
DNS and Dynamic Host Configuration Protocol (DHCP) are mission-critical in<br />
today’s service provider and enterprise networks<br />
New technologies are being introduced into the network: voice over IP<br />
(VoIP), video, cloud computing, virtualization, etc.<br />
<strong>Network</strong> operators need to accelerate provisioning and<br />
simplify service activation<br />
IP address management (IPAM) costs are rapidly accelerating,<br />
and manual processes and tools cannot scale<br />
<strong>Network</strong> operators are under pressure to reduce operating<br />
expenses (OpEx)<br />
<strong>Network</strong> operators have begun to transition<br />
from IPv4 to IPv6<br />

USGv6 Certification<br />
• <strong>Cisco</strong> Prime <strong>Network</strong> Registrar has achieved<br />
USGv6 (US Government IPv6) certification for its<br />
DHCP IPv6 server and now may be sold to US<br />
Government agencies.<br />
• Today, all civilian agency networks are required by<br />
law to be IPv6-capable. These US Government<br />
agencies are required to procure only IPv6 products<br />
that are USGv6 certified.<br />

Platform is extremely customizable and flexible to meet unique<br />
business needs<br />
Powerful extension support allows network operators to alter and<br />
customize DHCP server operations for both IPv4 and IPv6<br />
Extensions easily create new solutions such as billing, security,<br />
and lawful interception<br />
Extensive APIs and command-line interfaces (CLIs) enable<br />
integration points between the IPAM component and external<br />
systems for advanced IPAM automation<br />

Case Study: IBBS<br />
• IBBS is a managed services provider supporting small and medium-sized cable operators.<br />
Background<br />
• IBBS has 250 customers managing more than 1 million cable modems across North and South<br />
America. It automates the provisioning and diagnostics of these devices via a managed service.<br />
• <strong>Cisco</strong> ® <strong>Network</strong> Registrar has been an important part of this managed service since the business<br />
was established in 2001. The solution supports DNS and DHCP services as the basis of a<br />
DOCSIS ® cable modem provisioning system. <strong>Cisco</strong> <strong>Network</strong> Registrar is deployed as a single,<br />
multitenant cluster in the IBBS data center in Atlanta.<br />
Impact on customer<br />
and Results<br />
• The flexibility and scalability of <strong>Cisco</strong> <strong>Network</strong> Registrar have enabled IBBS to provide cable<br />
modem access services using a cloud model for the last 10 years with very little cost-long<br />
before it was called “the cloud.” Economies of scale and cost savings far exceed those of the<br />
competition.<br />
• Extension points give IBBS precise control over the DHCP requests coming in and the<br />
responses going out, based on very complex and detailed criteria.<br />
“<br />
All day, every day, <strong>Cisco</strong> <strong>Network</strong> Registrar reliably identifies each device and<br />
class of service, and then provides IP addresses and the right configuration files<br />
and profiles to keep each modem up and running.<br />

Case Study: Comcast<br />
Background<br />
• Comcast is a leading media and entertainment company, providing high-speed video, telephony,<br />
and Internet services to business and residential customers.<br />
• Comcast delivers more than 150,000 TV shows, movies, and other video content to over 49<br />
million customers across North America.<br />
• Comcast began planning the transition of its network to IPv6 in 2005. The ability to operate in<br />
“dual stack” mode, to accommodate IPv4 and IPv6 traffic, has been a critical component of its<br />
strategy.<br />
Impact on customer<br />
and Results<br />
• The flexibility and scalability of <strong>Cisco</strong> <strong>Network</strong> Registrar have enabled Comcast to transition to<br />
IPv6 seamlessly with no disruption to subscribers.<br />
• <strong>Cisco</strong> <strong>Network</strong> Registrar enabled Comcast to go well beyond feature parity between its<br />
management of IPv4 and IPv6 traffic, to actually advance its business by being able to<br />
implement advanced features, from device management to subscriber services, while running in<br />
dual stack mode.<br />
“<br />
With <strong>Cisco</strong> <strong>Network</strong> Registrar our IPv6 program was able to go well beyond feature<br />
parity and device management. We were able to design and implement features that<br />
enabled us to advance our business with new subscriber services.<br />
