U.S. Republican politicians on Thursday introduced a bill that would require Internet service providers and network operators to track the use of and maintain records for their publicly accessible wired and wireless networks. Two bills have been introduced... Each of the bills carries the title "Internet Stopping Adults Facilitating the Exploitation of Today’s Youth Act," and is referred to as the "Internet SAFETY Act."
A Tipping Point for the Internet? Catching the precise moment of a tectonic shift in a global system as large and important as the Internet may be viewed as an exercise in the improbable. However, I point out in this summary that I think we are precisely in the midst of such a shift...
At Cisco Networkers in Barcelona earlier this week, some of us saw a dragon try to wiggle out of its shell, provided you connected in IPv6 that is. A smile to Kame, the turtle which only danced under a IPv6 caress. Networkers 2009 saw more than 3000 attendants and a good complement of IPv6 presentations highlighted by a high powered plenary panel on the status of IPv6.
The beginning of the year saw IPv6 added to the DNS root, closing a major hole for IPv6-only communication. In mid-year, the US federal government's IPv6 mandate came into effect, requiring all federal IP backbones to support IPv6. While the mandate didn't have anywhere near the effect that many had hoped for, it did spur many vendors to add IPv6 support to their products. The amount of observed IPv6 traffic increased considerably, but we still lack good data for how much IPv6 is being used. So, where were we at the end of 2008?
Tunnel vision is a rather serious medical condition and the Internet or at least a number of service providers could be at risk if not treated soon enough. Symptoms of inter AS (Autonomous System) tunnel vision are many slower connections with IPv6 compared to IPv4 with some failing all together. Reason is that tunnels, especially inter-AS tunnels, can lead to long paths and non-optimal routing.
We don't give enough credit to people who will sacrifice themselves trying to plug the IPv4 dam with some NAT-putty. They even dream of a NAT66 filled afterlife. The growing IPv6 traffic trickle was given evidence at the recent RIPE 57 meeting in Dubai in a number of presentations, including a most edifying Google presentation. Noteworthy to see France with a 0.65% IPv6 penetration...
As we continue our ride toward the exhaustion of IPv4 addresses, Regional Internet Registries public discussion groups remain filled with endless discussions on how large swaths of allocated IPv4 addresses are unused, should be reclaimed or recycled one way or another, maybe be put on the free market and sold to the highest bidder or parsed out in more egalitarian controlled ways. Although everyone now accepts the notion of IPv4 address exhaustion, it seems to be for some an invisible glass wall and for others a gold brick wall worth the death of the internet to get a piece of it.
A decade has passed since Jon Postel left our midst. It seems timely to look back beyond that decade and to look forward beyond a decade hence. It seems ironic that a man who took special joy in natural surroundings, who hiked the Muir Trail and spent precious time in the high Sierras was also deeply involved in that most artificial of enterprises, the Internet.
IPv6 is in the news because the mainstream media have started to pick up the fact that IPv4 will be fully allocated in the next two or three years. And IPv6 deployment is important if we want to keep the Internet growing sustainably. So where is IPv6 deployment most evident?
It's fascinating to watch the Internet technical community grapple with policy economics as they face the problems creating by the growing scarcity of IPv4 addresses. The Internet Governance Project (IGP) is analyzing the innovative policies that ARIN, RIPE and APNIC are considering as a response to the depletion of IPv4 addresses.
