Anecdotally, it would take about a week for a single machine to ping sweep the Internet. That would be approximately 4 billion IP addresses, essentially the whole Internet. In theory, this includes every single military address, every single ISP, every home user, and every mobile device. Such a port sweep does not include all options, UDP, and Nmap Scripts, as that would take too long. But what if I want to run the same scan to my home IPv6 range? It will have a /64 allocated to it, or about 18 quintillion addresses. Let’s compare a sweep of the entire Internet with my home IPv6 range:
- The Internet: 2^32 = 4,294,967,296 
- The home range from my ISP: 2^64 = 18,446,744,073,709,551,616 
A stark difference! So, how will I scan this? Is that just one network? I am Moses Hernandez, and this is one of my tips and tricks in this series. This post is about the venerable Nmap. Read More »

Market trends are impacting how we collaborate. A key trend is the need for pervasive video delivered to every desktop, so that all users can benefit from rich interactions. A second important trend is towards cloud services, the ability to deploy and access services and applications from the cloud.
These trends are truly driving a new paradigm in desktop collaboration, and Cisco is leading this industry evolution with our recent announcement of the Cisco Desktop Collaboration Experience DX650. This new Android-based desktop endpoint – our next-generation IP phone – delivers Cisco’s entire suite of collaboration capabilities through an intuitive touch screen. It combines two things we all know and love Read More »

Wi-Fi is a convenience many expect to encounter whether they are at work, at home, or even out and about, say, shopping. Connecting to the internet from anywhere, at any time, is the norm these days, and for good reason. Smart devices are becoming more and more popular, and people are bringing these devices with them everywhere. So, how can the business world benefit from this? First, give the people what they want. Offer a robust wireless network so your customers are able to connect seamlessly. When you provide this, you are able, in turn, to engage with them. Read More »

At Microsoft Management Summit 2013 in Las Vegas this week, Cisco is showing a host of new technology innovations and integrated solutions for the virtualized data center. By bringing Cisco virtual networking and UCS solutions together with Microsoft cloud solutions, we are expanding the market for our technology, while providing more technology options and flexibility for our customers.
Critical to our Microsoft infrastructure strategy is the Nexus 1000V virtual switch for the Hyper-V hypervisor in Windows Server 2012 and integrated with System Center Virtual Machine Manager (SCVMM). Cisco’s Microsoft-oriented data center architectures, rooted by UCS and Nexus 1000V are proven to save customers’ OpEx and CapEx.
Nexus 1000V for Hyper-V
Our new version of Nexus 1000V for Hyper-V has been in wide use for the last several weeks since we opened up the public beta to all volunteers. The availability of Nexus 1000V and these go to market initiatives with Microsoft are the culmination of 3 years of joint effort between the companies, including developing the ecosystem for completely integrated solutions. These fully integrated solutions include VSPEX, FlexPod (with EMC and NetApp) that enable channel partners to deliver value to end customers.
The feedback we’ve been getting from the beta users of the new Nexus 1000V has been really positive. If you missed the insights from Microsoft MVP, Damian Flynn, when he presented at one of our online webinars, you can hear him talk about his experiences here.
What we consistently hear from customers is the Cisco Nexus 1000V for Microsoft Hyper-V:
- Offers consistent operational experience across physical, virtual, and mixed hypervisor environments
- Reduces operational complexity through dynamic policy provisioning and mobility aware network policies
- Improves security through integrated virtual services and advanced Cisco NX-OS features

If you had US$15,000 to take a trip anywhere in the world, where would you go? I’ve always wanted to visit Perth, Bangalore, and Brasilia myself, but sadly, I’m not elligable to win the Unified Access Challenge. However, if you’re reading this -- you probably are! Basically, you watch an accelerated TechWiseTV episode with JimmyRay Purser, Robb Boyd (with a short Ike video too), and then answer a few questions about Unified Access.
The challenge is open for three more weeks and there are a few versions you need to choose from. If you’re a Cisco Partner you need to take the Partner version. If you don’t know whether you’re a partner or not, you’re probably not, so don’t fret. Because for non-partners we have the challenge in both English and Spanish: Read More »
