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»

Some Internet Measurements

At APNIC Labs we've been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP. The intent of this particular set of data collections is to allow the data to be placed into a relative context, displaying comparison of the individual measurements at a level of geographic regions, individual countries, and individual networks. more»

Breaking It Down: the IANA Transition in Practical Pieces

As a Regional Internet Registry, APNIC has a strong interest in the Internet Assigned Numbers Authority (IANA), and the services it provides. We have followed the progress of IANA carefully, in particular through the evolution of ICANN, and the various steps taken by the US Government to reduce its level of oversight. Along with other RIRs, through the NRO, we have made several public statements about the IANA and its future development, mostly in response to US Government enquiries. more»

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more»

The IETF's *Other* Diversity Challenge

The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? more»

Webinar Tomorrow (May 22) - IPv6 and Telecom: IPv4 is Finally Running Out. Now What?

What is the impact of IPv6 on telecommunications, VoIP, unified communications, etc? Why should telecom operators care about IPv6? What VoIP systems already support IPv6? What efforts are underway within organizations like the IETF and the SIP Forum to ensure that telecommunications can work over IPv6? more»

IP Addresses in Cars, Car Manufacturers as Internet Registries? - Another Need for IPv6 Now!

I recently came across an interesting piece about the use of IP addresses in the Tesla model S. The part that caught my attention and led to this post is that the car uses the private IPv4 address subnet 192.168.90.0/24 to address different nodes e.g. the centre console is 192.168.90.100 and the dashboard/navigation screen is 192.168.90.101. Put your geek hat on for a moment as you ponder that! more»

IANA Transition Set to Disrupt ICANN Operations

The US Government's decision to transition its oversight of the IANA function to a multi-national, multi stakeholder organisation is set to impact ICANN's standard operations. On April 25, ICANN Board Chair Steve Crocker send an email to the ICANN community leaders suggesting changes to the agenda for the upcoming 50th International ICANN meeting, set to be held in London from June 22 to 26. more»

The Importance of IP Resource Planning in Government ICT Strategic Plans

It seems everywhere I turn, there's someone throwing around statistics for how the Internet and broadband will drive economic growth, create jobs, end world hunger and bring world peace (ok, maybe not the later). Sure enough, government officials are buying into that rhetoric and extending it in initiatives like national broadband strategies, cybercrime and cybersecurity plans as well as e-governance strategies. more»
