Is It Time to Create a Market for IPv4 Addresses?

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. more»

The IPv6 Inconvenient Truth: Deployment Could Cause Network Problems, Threaten Cybersecurity

The move to Internet Protocol version 6 (IPv6) could have a profound affect on the Internet, breaking it up into islands of connectivity and threatening cybersecurity in the process, according to Jeff Young, a senior analyst at the Burton Group. As the IPv4 free address pool continues to dwindle, enterprises can expect to see IPv6-only hosts on the Internet within a three-year timeframe, Young said. In the report, "IPv4 Address Exhaustion: An Inconvenient Truth," Young addresses the incompatibility of IPv4 and IPv6 and some of the problems that need to be addressed during the changeover. more»

NIST Releases a Profile for IPv6 in the U.S. Government for Comment - Comments Due Feb. 29

The National Institute for Standards and Technology (NIST) has released a second draft of a proposed standards profile to support the implementation of IPv6 by government agencies. "NIST developed the 'profile' to help ensure that IPv6-enabled federal information systems are interoperable, secure and able to co-exist with the current IPv4 systems." ...The White House's Office of Management and Budget declared in 2005 that all federal agencies shall migrated to IPv6 by June 30, 2008... more»

Department of Commerce Begins Re-Solicitation for IANA Contract

In follow up to the cancelation of IANA Contract RFP last month, the United States Department of Commerce (DoC), National Telecommunications and Information Administration (NTIA) have just issued solicitation of the contract. more»

Cloud Security Hinges on IP Addressing

In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more»

Measuring World IPv6 Day - First Impressions

The RIPE NCC took active measurements of World IPv6 Day participants before, during and after World IPv6 Day (in cooperation with CAIDA). We selected 53 participants and performed periodical A and AAAA DNS lookups and HTTP fetches from 40 servers worldwide. For HTTP, we fetched data over IPv4 and IPv6. These provide important control points... more»

ARIN Launches WHOWAS: Trial Service Providing Historical Information for a Given IP Address

American Registry for Internet Numbers (ARIN) is running a trial service that gives users access to historical IP whois data – that is, it will tell you who was responsible for an IP address or block of IPs. The service is not automated and if you want to access it you will need to submit a request via email with information about not only what you want to know, but why you are interested in accessing the information. more»

IPv6 Floating on the Ethernet

Remarkable how Ethernet has evolved and been widely adopted over this quarter of a century period extending its reach from LAN to MAN to WAN and from 10meg to 10gigE. One has to credit the IEEE for quite an efficient job as a standards body. Over in the IP world, this month of March will see IETF 74 meet in San Francisco and continue to ponder transitions, address translations, double translations, even carrier grade translations... more»

IPv6: Circling the IPv4 Wagons for a Last Stand

The last remaining stocks disappear from the shelves more quickly than ever before . . . IPv4 addresses that is. As the ARIN met in Toronto in April, an inordinate amount of time was spent yet again debating proposals on how to handle the dwindling stock of IPv4 addresses. I get the distinct impression that some people will still be tabling proposals and discuss the issue long after the last IPv4 block has been allocated by IANA and even the RIR's themselves. more»

The Company You Keep

This story started earlier this year, with a posting to the Australian network operators' mailing list, asking if anyone had more information about why the web site that was operated by an outfit called "Melbourne Free University" was inaccessible through a number of major Australian ISPs. When they asked their local ISP if there was some issue, they were informed that "this was due to an Australian government request, and could say no more about it." more»

Verizon: Advent of 4G LTE, WiMAX-Based Devices Will Only Increase the Need for IPv6

Verizon Business has a message to companies still reluctant to migrate their networks to IPv6: You're better off doing it now than later. William Schmidlapp, Verizon Business's product manager for Internet dedicated access services, says that the advent of 4G LTE and WiMAX-based devices will only increase the need to switch over to IPv6, since each of those devices will require its own IP address... more»

ARIN Statement on the Future of Addressing Policy

ARIN has just released a statement on the future of addressing policy. Specifically addressing the future of IPv4 addressing. What ARIN does is to emphasize the current policies and say they will be enforced even stronger than today if needed. I.e. there is no announcement of a change in policy. more»

Significant Chunk of IP Address Space Hijacked by Notorious Mass Emailing Company

Internet address space long ago issued to San Francisco Bay Packet Radio, an organization that was involved way back in the 1970s in testing ARPANET, a predecessor to the global commercial Internet that we all use today. That organization was given the rights to do whatever it wanted with 134.17.0.0/16 address block. That entire swath of Internet space is now registered to an entity in Westminster, Colo., called SF Bay Packet Radio LLC, but except for a similar name, this company has no relation to San Francisco Bay Packet Radio... ? more»

Measurement Results from World IPv6 Launch

As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. more»

Do We Need An IPv6 Flag Day?

In recent interviews about World IPv6 Launch I've been asked by several different people whether or not I think there needs to be some kind of a "Flag Day" on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6). I don't think a flag day is needed. World IPv6 Launch is just the right thing. It's worth looking at some previous flag-type days to get a better sense of why. more»
