The Changing Role of IP Addresses in the Architectural Evolution of the Internet

I work at APNIC, the Regional Internet Registry that serves the Asia Pacific Region. APNIC provides common infrastructure services for the region that support the unique assignment of IP address blocks to Internet network operators within our region through the operation of an address registry. In short, IP addresses are what we do. So, when there are discussions in technology circles about evolving the Internet's address model in varying ways,... more

Addressing 2012: Another One Bites the Dust

Time for another annual roundup from the world of IP addresses. What happened in 2012 and what is likely to happen in 2013? 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

Emerging Communications Technologies

A "New IP" framework was proposed to the ITU last year. This framework envisages a resurgence of a network-centric view of communications architectures where network-managed control mechanisms moderate application behaviors. It's not the first time that we've seen proposals to rethink the underlying architecture of the Internet's technology (for example, there were the "Clean Slate" efforts in the US research community a decade or so ago) and it certainly won't be the last. more

Ongoing Internet Emergency and Domain Names

There is a current ongoing Internet emergency: a critical 0day vulnerability currently exploited in the wild threatens numerous desktop systems which are being compromised and turned into bots, and the domain names hosting it are a significant part of the reason why this attack has not yet been mitigated. This incident is currently being handled by several operational groups. This past February, I sent an email to the Reg-Ops (Registrar Operations) mailing list. The email, which is quoted below, states how DNS abuse (not the DNS infrastructure) is the biggest unmitigated current vulnerability in day-to-day Internet security operations, not to mention abuse. more

The Internet Running Out of Everything?

We know that the Internet is running out of IPv4 addresses and that some in our community check twice a day Mat Ford's doomsday clock or spend an hour once a week reading the tea leaves based on Geoff Huston's exhaustive data compiled at Potaroo. Like with global warming, there is still a school of thought out there arguing that this running out of IP addresses is just fear mongering and that we are not really running out of IPv4 addresses as a NATted world is more than adequate to run the Internet for the foreseeable future. We know that the Internet is running out of AS... more

IPv4 Historical Imbalances and the Threat to IPv6

It is an open secret that the current state of IPv4 allocation contains many accidental historical imbalances and in particular developing countries who wish to use IPv4 are disadvantaged by the lack of addresses available through ordinary allocation and are forced into purchasing addresses on the open market. As most of the addresses for sale are held by organisations based in the developed world, this amounts to a transfer of wealth from the developing world to the developed world, on terms set by the developed world. more

An Open Letter to Big Tech CFOs: Save the Internet Before You’re Forced

Dear Chief Financial Officers of tech giants, the internet is in crisis, and you can lead your organization to help solve the problem. You'll be well compensated, and you'll enjoy massive public relations benefits. I fear that if you don't, global governments will force your hand. There is a shortage of available IPv4 addresses but we are years away (possibly a decade or more) from IPv6 viability and adoption in North America. more

7 Must Have Attributes of an IP Address Management System

Exponential growth of networks combined with the complexity introduced by IT initiatives e.g. VoIP, Cloud computing, server virtualization, desktop virtualization, IPv6 and service automation has required network teams to look for tools to automate IP address management (IPAM). Automated IPAM tools allow administrators to allocate subnets, allocate/track/reclaim IP addresses and provide visibility into the networks. Here are some examples of what a typical IPAM tool can do... more

At the ARIN Meeting

I have been attending the American Registry for Internet Numbers (ARIN) meeting in Toronto. ARIN is one of the RIRs, i.e., the Internet address registry and policy making authority for North America. Although I have observed and participated on RIR lists for some time and interacted with RIR representatives at ICANN, WSIS and IGF, this is the first time I have been able to attend a meeting. I'm glad I did. more

IPv6… the Year NAT-Enforced IPv4 Dam Showed Seepage

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... more

Graph Shows Decline of IPv4 Has Been Mostly Linear

As the free pool of IPv4 addresses reaches its end, we looked at the evolution of the amount of unassigned IPv4 address space over time. By 'unassigned', we mean address space not yet allocated to a Local Internet Registry (LIR) or assigned to an end user. LIRs are typically Internet Service Providers or enterprises operating an IP network. See our findings in the graph below... 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

More IPv6 Warnings on Why Organizations Must Plan Transition Now

The IPv6 Portal reports on a paper titled "The Choice: IPV4 Exhaustion or Transition to IPv6", written by Jordi Palet, warning that organizations must start planning for IPv6 now or "be aware that some already have, and you are beginning to be at a disadvantage." From the report: "This is going to affect the business of existing Internet Service Providers (ISPs) and to a greater extent, at a certain point in time, the creation of new ISPs. As a consequence if may have a deeper impact in developing regions (Africa, Asia and Latin America/Caribbean) where the penetration of the Internet is not yet so widespread." more

Notes from NANOG 83

The network operations community is cautiously heading back into a mode of in-person meetings, and the NANOG meeting at the start of November was a hybrid affair with a mix of in-person and virtual participation, both by the presenters and the attendees. I was one of the virtual mob, and these are my notes from the presentations I found to be of personal interest. I hope you might also find them to be of interest as well... The year 2021 has not been a good year for Internet outages. more

IP Address Intelligence Burdening Content Providers with Regional Laws?

I've been looking into IP address filtering by content providers. I understand that IP addresses can be attached with confidence to geographical locations (at the country level, at least) about 80% of the time. You have to make up the rest with heuristics. So there are companies that are in the business of packaging those geolocation heuristics for sites. ...How widely are these services used? ...does it now make sense to put content sites to the burden of complying with the laws applicable to the people/machines they know are visiting them? more
