RFC 1918 Address Space: Why It Was Needed then and How It Will Change in IPv6!

Recently, my firm has seen a lot of interest come from Enterprises seeking IPAM/DNS tools. We predicted that IPv6 adoption and the need for automation software/tools would follow the Internet ecosystem's supply chain starting with Service Providers consisting of ISPs, I/PaaS, ASPs, then content providers (mostly a service really), then Enterprises, followed by SMBs & Consumers. While good for business, it has also forced us to revisit and think thru many TCP/IP protocol standards...

Using Domain Filtering To Effect IP Address Filtering

In Taking Back The DNS I described new technology in ISC BIND as of Version 9.8.0 that allows a recursive server operator to import DNS filtering rules in what ISC hopes will become the standard interchange format for DNS policy information. Later I had to decry the possible use of this technology for mandated content blocking such as might soon be the law of the land in my country. I'm a guest at MAAWG this week in San Francisco and one of the most useful hallway discussions I've been in so far was about the Spamhaus DROP list.

How Many IPv4 Addresses Does the RIPE NCC Have Left?

Since IANA ran out of IPv4 addresses, people are increasingly aware of how short the remaining lifetime of IPv4 is. With World IPv6 Day taking place this week, the issue has come into even sharper focus. Since March 2011, the RIPE NCC has been publishing the size of its pool of available IPv4 addresses. All five Regional Internet Registries (RIRs) regularly publish the status of their IPv4 address pools. In the image below, you can see how the number of IPv4 addresses in the RIPE NCC pool changes over time.

DHCP for IPv4 vs. IPv6 - What You Need to Know

Dynamic Host Configuration Protocol (DHCP) is a protocol intended to enable machines (servers, game consols, etc) wishing to be "online" the ability to request Internet Protocol information from a DHCP server automatically. ... In this article we will begin to outline some of the fundamental differences between DHCPv4 and DHCPv6, explore historical uses of DHCPv4 and how those concepts will adapt/change in IPv6.

What is Internet Protocol Address Management?”

The number of web-based devices is expanding at an exponential clip, virtualization is making a very static environment dynamic, and now with the exhaustion of IPv4 and the oncoming complexities of IPv6 network operators must reevaluate what IP Address Management (IPAM) really is. The goal of this post is to define the various functions that make up IP Address Management.

IP Addressing in the New Age of Scarcity

This is the prepared opening statement given on behalf of Depository, Inc. at the panel discussion "IP addressing in the new age of scarcity" in the context of Internet governance and public policy at the Global Internet Governance: Research and Public Policy Challenges for the Next Decade Regional Conference held at the American University School of International Service on Thursday, May 5th, 2011 between 11:00 a.m. to 12:15 p.m. with Prof. Milton Mueller moderating and on the panel as well was John Curran, President and CEO of ARIN and Michael Froomkin, Professor of Law, University of Miami School of Law.

IP Addresses as Money

It's no secret that the supply of IPv4 addresses, on which the Internet has been based since the dawn of digital time, is rapidly running out. The official replacement is much larger IPv6 addresses, but I can report from experience that the task of switching is not trivial, and for a long time there will be a lot of the net that's only on IPv4. So once the initial supply of IPv4 addresses run out, and the only way to get some is to buy them from someone else, what will the market be like?

IPv6 RIPEness: One Year Later

A year ago, the RIPE NCC introduced IPv6 RIPEness -- a system that rates IPv6 deployment of Local Internet Registries (LIRs)... Now, one year later, the numbers have gone up... In absolute numbers: more than 3,000 LIRs have IPv6 address space. This means that the RIPE NCC has made more than 1,100 IPv6 allocations within 12 months.

Court Approves Nortel’s Sale of IPv4 Addresses to Microsoft

Yesterday morning (26-April-2011), in US Bankruptcy Court for the District of Delaware, Judge Kevin Gross signed an order authorizing Nortel's sale of IPv4 addresses to Microsoft. This is an important moment for the Internet community, as it represents the beginning of a new market-based mechanism for the distribution of scarce IPv4 address resources. As the various Regional Internet Registry (RIR) organizations exhaust their supply, traditional "needs-based" distribution will become impossible.

Microsoft Direct Access: Is it Heaven or Hell for IPv6?

I must confess, during the past couple of years I have highlighted the VPN-solution Direct Access (DA) from Microsoft as a killer application for IPv6. I still have hope for this solution, but as I now have had the chance to study the UAG/DA-solution more closely and in practical implementation, I must also highlight some issues for Microsoft to handle. My conclusion is that using DA today brings difficulties when it comes to an organization that already has, or wants to, deploy native IPv6 internally.
