Managing the IPv4/IPv6 address space resource requires an advanced tool that intelligently allocates, assigns and tracks the address blocks and individual IP addresses deployed on modern IP networks. 

When multiple receivers are required to get the same data at approximately the same time, multicast is a more efficient way of delivering data than unicast. 

Check out this white paper for a discussion on network changes; IP address management; Core Network Services solutions; and the benefits of integrated, automated IP. 

Our new IP Address Tracker frees you from the evils of spreadsheets, delivering powerful and simple-to-use features that give you a unified view of your IP address space and that enable you to manage it -- for free!

No longer a thing of the future, IP Convergence is now the cost of doing business. Unified Communications (UC) is the target destination for many enterprises. And while the concept is no longer new, IP convergence remains the first major step on that path. 

In this technical podcast you'll learn key things to consider as part of a business migration to voice-over-IP - designing your data network for QOS, traffic analysis and capacity planning, four possible architecture models, security requirements, and VoIP design components. 

In this white paper, we'll take a look at access control lists, often referred to as access lists or ACLs (sometimes pronounced "ackels"). 

IT executives no longer need to justify their use of Voice over IP—the technology works. It saves companies money, and it enables communication across global boundaries. As companies grow more global, and workers more virtual, employees must be able to communicate with co-workers, partners, customers and suppliers anytime, anywhere. 

This paper presumes that your enterprise already has a data network security policy in place. It examines the many different settings that are available to help secure the Cisco IP Phones from potential hacker attacks, and it looks at a selection of Cisco secure infrastructure technologies that are especially useful for protecting voice systems. 

With the momentum of IP convergence and the movement toward an all digital world, professional communication systems combining telephony over IP, e-mail, instant messaging and audio/video conferencing services are sparking serious interest due to the benefits they offer. Read on to learn more. 

Currently over 600 Orange Business Services customers use their VPNs to transport voice and data. Some use a do-it-yourself model; others use a fully managed model. If you're looking for value, the fully managed approach is the less costly and higher quality alternative. Read this paper to find more details about pros and cons of each choice.
