An insider’s guide to the private IPv4 market

We’ve been hearing about the impending depletion of IPv4 addresses for years, but that day is finally upon us -- the free supply of IPv4 numbers in North America will be completely gone within a month or two.However, as the world slowly transitions to IPv6, there’s no cause for alarm. A significant quantity of unused, previously allocated IPv4 numbers are readily available for re-distribution to IP network operators that need them. And an active private market for IPv4 addresses has emerged to allow companies with these excess IPv4 numbers to sell them to those in need.+ ALSO ON NETWORK WORLD Infographic: IPv4 vs IPv6 +To read this article in full or to leave a comment, please click here

Senate to return early to debate phone dragnet

The U.S. Senate will return early from a week-long recess in a last-ditch effort to extend provisions of the Patriot Act that the National Security Agency have used to collect millions of domestic telephone records over the past nine years.The Senate is scheduled to resume debating whether to extend or amend Section 215 of the Patriot at 4 p.m. ET Sunday, hours before that part of the counterterrorism law is due to expire. The Senate was previously scheduled to return from an extended Memorial Day break on Monday, but Section 215 of the Patriot Act expires at 12:01 a.m. that day.It’s unclear what direction the Senate debate will take. As of Wednesday morning, Senate Majority Leader Mitch McConnell hadn’t announced what votes will be taken Sunday evening.To read this article in full or to leave a comment, please click here

Let’s Review: EIGRP Named Mode

My next stop on my CCIE: R/S Written review. EIGRP, the big change here is EIGRP Named Mode it’s the same EIGRP with a new shiny cover. So , let’s jump in. To start the new named mode configuration we need to define the ‘named instance’ compared to defining the autonomous system out of the gate. […]

How a Florida fender-bender could threaten Uber’s business model

A March collision between a Mitsubishi Outlander and a scooter in the Miami area could have huge repercussions in Silicon Valley. According to reports in Buzzfeed and elsewhere, the minor accident caused only a few thousand dollars in damages. But it could have a nationwide impact on the business models of ridesharing and other app-driven services. Because the SUV was dropping off Uber passengers at the time, the driver asked the company's insurance to cover the costs. But Uber and the driver couldn't come to an agreement, so—unable to keep driving until the vehicle was fixed or replaced—Darrin McGillis ended up filing an unemployment insurance claim against Uber and a subsidiary. That forced the Florida Department of Economic Opportunity to determine whether the driver was actually an employee of Uber, not an independent contractor, as the company claims. Last week, the Florida DEO's initial determination held that McGillis was indeed an employee, not a contractor.To read this article in full or to leave a comment, please click here

A match made in heaven? 10 tech mergers that defined the industry

AOL, back on the marketImage by REUTERS/Brendan McDermidAn unexpected merger between AOL and a storied incumbent? You'd be forgiven for thinking you'd gone back to the turn of the century, but no, that happened earlier this month. Whatever the reasons behind the AOL-Verizon merger -- for all the talk of AOL's content offerings, its advertising platform may be the big prize -- at a mere $4.4 billion dollars the deal is a pale shadow of the $164 billion blockbuster AOL-Time Warner merger that marked the height of dot-com hubris.To read this article in full or to leave a comment, please click here

MPLS “No Label” vs “Pop Label”

I like MPLS. And I don’t necessarily mean as a solution to solve a problem, but as something to configure in the lab. It’s fun to build things that do something when you’re done. Setting up OSPF or EIGRP and being able to traceroute across routers is meh. But configuring MPLS with all the associated technologies — an IGP, LDP, MP-BGP, — and then getting all of them working in unison… when you get the traceroute working, it’s rewarding.

Here’s something to keep an eye out for when you’re troubleshooting MPLS: An LFIB entry (that is, the Label Forwarding Information Base) that states “No Label” versus one that states “Pop Label”. These mean very different things and can be the difference between a working Label Switched Path (LSP) and a non-working LSP.

The Topology

Here’s the topology I’m working with:

MPLS-no-label-vs-pop-label-topology

Click to Enlarge

 

R21 and R8 are Customer Edge (CE) routers and they communicate through the MPLS network in the “BRANCHES” VRF. R4 and R7 are Provider Edge (PE) routers and R1, R5, and R6 are Provider (P) routers.

Working State

I’m going to examine traffic going from R8’s 10.1.8.8 address and destined to R21’s 10. Continue reading

Computer chips made of wood promise greener electronics

U.S. and Chinese researchers have developed semiconductor chips that are nearly entirely made out of wood-derived material.Aside from being biodegradable, the chips could be produced for only a fraction of the cost of conventional semiconductors, according to the group of 17 researchers, mostly from the University of Wisconsin-Madison with others from the U.S. Department of Agriculture.The researchers used a cellulose material for the substrate of the chip, which is the part that supports the active semiconductor layer. Taken from cellulose, a naturally abundant substance used to make paper, cellulose nanofibril (CNF) is a flexible, transparent and sturdy material with suitable electrical properties.To read this article in full or to leave a comment, please click here

Open vSwitch Database Management Protocol (OVSDB) 101

Open vSwitch Database Management Protocol (OVSDB, RFC 7047) is often mentioned together with other semi-magic SDN tools that will bring everlasting peace to the chaotic world of networking. In reality, it’s just a database access/update protocol (think SQL with JSON encoding) with an interesting twist: a client can request notifications about table or row updates, replacing periodic database polling with a pub-sub solution.

Some notes about Wassenaar

So #wassenaar has infected your timeline for the past several days. I thought I'd explain what the big deal is.

What's a Wassenaar?


It's a town in Europe where in 1996 a total of 41 nations agreed to an arms control treaty. The name of the agreement, the Wassenaar Arrangement, comes from the town. The US, Europe, and Russia are part of the agreement. Africa, Middle East, and China are not.

The primary goal of the arrangement is anti-proliferation, stopping uranium enrichment and chemical weapons precursors. Another goal is to control conventional weapons, keeping them out of the hands of regimes that would use them against their own people, or to invade their neighbors.

Historically in cybersec, we've complained that Wassenaar classifies crypto as a munition. This allows the NSA to eavesdrop and decrypt messages in those countries. This does little to stop dictators from getting their hands on strong crypto, but does a lot to prevent dissidents in those countries from encrypting their messages. Perhaps more importantly, it requires us to jump through a lot of bureaucratic hoops to export computer products, because encryption is built-in to virtually everything.

Why has this become important recently?


Last year, Wassenaar Continue reading
