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 »

Every day, more partners are flocking to the Cisco Partner Communities. Why? Well, the communities are staffed with knowledgeable and friendly Cisco community managers who can help answer your most challenging technology questions, give you details on Cisco programs, and keep you informed.
Yep. The information you need is right there for the taking. If that’s not enough, you can visit the extensive documents library to download the information or presentation you need.
We’ve also cleaned up things a bit, too. If you haven’t visited the communities yet, or haven’t been by in awhile, we’ve made it easier to navigate, been straightening up and streamlining over the past few months, based on feedback from partner users.
Come take a quick look:

Twitter has been cracking down on third party apps as of late for violating their Terms of Service. This has resulted in suspension of those services. While Twitter applications certainly make all of our lives a little easier, we can live without them, at least for a little bit.
While we can’t easily check out the specifics of our followers or schedule tweets without our precious apps, we can still monitor the conversation. The old school way. Below is a list of search operators provided by Twitter that will help you keep tabs on the conversation while your apps may be in the time out chair or just unavailable in general. Learn the basics of search and cut through the noise of Twitter under any circumstance.

What if you went into your office and all of the meeting rooms were empty? Yet when you looked around, you could see work being done, ideas being shared, and deadlines being met.
More and more at Cisco, this is how a normal workday looks for many of our employees. Through the capabilities of Cisco WebEx Meeting Center, Cisco employees now work together virtually more often.
We use WebEx Meeting Center in several ways. Work teams that have members located around the world use it for audio or video conferences, or for online collaboration sessions, where they share presentations, documents, and desktop applications. Because it is easy to start a WebEx session, I can collaborate with my team at any moment.
We also use WebEx Event Center to hold large, virtual meetings, such as our annual global sales conference that involved 19,000 participants worldwide. And because users can access the WebEx Meeting Center service over the Internet, we have gained a simple, cost-effective way to communicate for business continuity during a pandemic, a natural disaster, or other situation when employees can’t go to work in a Cisco office.
WebEx Meeting Center is deployed as a hosted service on the WebEx collaboration cloud. This means we no longer need to maintain the network infrastructure for online collaboration, we don’t have to worry about supporting peak traffic loads, and users can access new features as soon as they are available.
Usage levels have exploded as WebEx Meeting Center has proven to be very popular among Cisco employees. That popularity is producing great value for our business, especially for cutting our travel budget in half. But it may make Cisco’s meeting rooms very lonely places to be.
