Media (R)evolutions: The internet gets a new postal system

New developments and curiosities from a changing global media landscape: People, Spaces, Deliberation brings trends and events to your attention that illustrate that tomorrow's media environment will look very different from today's, and will have little resemblance to yesterday's.

Back in the 1970s and 80s, an Internet standard communications protocol, IPv4 or Internet Protocol Version 4, was conceived to interconnect research universities and government facilities in the United States. IPv4 assigns each device connected to the Internet with its own unique identification number, known as an IP address, so that devices can find and communicate with one another. At the time, the quite large number of IP addresses that IPv4 provided for— 4.3 billion— seemed like an almost limitless number that would never run out.

Flash forward to today in which the world population surpasses 7 billion people and the Internet of Things, wearables, and other advances in technology— which all require that each device has its own IP address— and the pool of IP addresses has been exhausted.  Devices now sometimes share IP addresses, resulting in delays and difficulties in routing Internet traffic and limitng the growth of the Internet— particularly in emerging markets. Mobile technologies, which are particularly important to developing countries are held back because network providers cannot assign unique addresses to every mobile device. 

This is where IPv6 comes in.  Not only does it substantially increase the number of addresses, but it also enables more efficient routing, more efficient use of modern hardware, and the ability to support modern networking concepts like mobility.  In July 2015, the American Registry for Internet Numbers (ARIN), the regional organization in charge of assigning IP addresses in North America, began wait-listing applicants because it has exhausted its supply of IP addresses under IPv4.  The Asia-Pacific, Europe, and Latin America regions ran out before that.

From IPv4 to IPv6

The Transformative Impact of Data and Communication on Governance: Part 3
Brookings Institution
How do digital technologies affect governance in areas of limited statehood – places and circumstances characterized by the absence of state provisioning of public goods and the enforcement of binding rules with a monopoly of legitimate force?  In the first post in this series I introduced the limited statehood concept and then described the tremendous growth in mobile telephony, GIS, and other technologies in the developing world.  In the second post I offered examples of the use of ICT in initiatives intended to fill at least some of the governance vacuum created by limited statehood.  With mobile phones, for example, farmers are informed of market conditions, have access to liquidity through M-Pesa and similar mobile money platforms.

Cashing in: why mobile banking is good for people and profit
The Guardian
Using digital finance to tackle development problems can improves lives, and offer innovative companies handsome rewards. Whether it is lack of access to water, energy or education, development professionals are well versed in the plethora of challenges facing billions of people. The traditional approach to solving these problems has been to think big – in terms of the millennium development goals, government aid programmes, or huge fundraising campaigns. But there are dozens of startups and larger companies with innovative ideas who are approaching these challenges in new ways using digital finance.
