New Trend: Vanity IPv6 Addresses

It's like a vanity license plate, but for your IP address. Previously under IPv4 DNS registration, users were limited to only using numbers. However, with the height of IPv6 underway users are getting creative with their newfound use of characters. Although you can only use characters A-F, it only takes a little creativity to find ways around this. more»

IPv4 Exhaustion, 5 Implications for Africa Running out Last

I spend most of my time teaching engineers in different countries how to plan and deploy IPv6 networks. Over the last two years, I have been speaking more and more to non-engineers. These are either technology executives who sense that they need to do something about this "IPv6" thing, or government IT leaders who want to understand what the problem is and more importantly, what they could do. The most impactful part of these these exchanges is when I get these managers to understand the implications of IPv4 address exhaustion to their organisations. more»

An Update on IPv6

In the coming weeks another Regional Internet Registry will reach into its inventory of available IPv4 addresses to hand out and it will find that there is nothing left. This is by no means a surprise, and the depletion of IPv4 addresses in the Internet could be seen as one of the longest slow motion train wrecks in history. The IANA exhausted its remaining pool of unallocated IPv4 addresses over four years ago in early 2011, and since then we've seen the exhaustion of the address pools in the Asia Pacific region in April 2011, in the European and the Middle Eastern region in September 2012, in Latin America and the Caribbean in May 2014 and now it's ARIN's turn... more»

Apple and IPv6 - Not Quite There Yet

It's Apple's Developers Conference time again, and in amongst the various announcements was week, in the "Platforms Status of the Union" presentation was the mention of Apples support of IPv6. Sebastien Marineau, Apple's VP of Core OS told the conference that as far as IPv4 addresses are concerned, exhaustion "is finally here", noting that this already started in 2011 in the Asia Pacific while in North America IPv4 address exhaustion is imminent. Sebastien noted that it's really important to support IPv6 in devices and applications these days... more»

Notes from NANOG 64

The North American Network Operator's Group held its 64th Meeting in San Francisco in early June. Here's my impressions of some of the more interesting sessions that grabbed my attention at this meeting... At the start of the year, the US FCC voted to reclassify Broadband Internet access services under Title II of the US Telecommunications ACT -- effectively viewing Internet access providers as common carriers, with many of the rights and responsibilities that goes with this classification. more»

The Longevity of the Three-Napkin Protocol

It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more»

Addressing 2014 - And Then There Were 2!

Time for another annual roundup from the world of IP addresses. What happened in 2014 and what is likely to happen in 2015? This is an update to the reports prepared at the same time in previous years. So lets see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. more»

Some Observations from NANOG 62

NANOG 62 was held at Baltimore from the 6th to the 9th October. These are my observations on some of the presentations that occurred at this meeting. .. One of the more memorable sides in this presentation was a reference to "map" drawn by Charles Minard in 1869 describing the statistics relating to the Napoleonic military campaign in Russia, and the subsequent retreat. more»

Where is Metadata Anyway?

I can't help but think that the situation in this rather old joke applies very precisely to the current Australian efforts to compel network operators, through some contemplated regulatory instrument, to record and retain network-collected data about their customers' online activities. What I'd like to examine here the emerging picture that while networks, and network operators, make convenient targets for such surveillance efforts, the reality of today's IP network's are far more complex, and Internet networks are increasingly ignorant about what their customers do. more»
