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»

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»

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»

Business Case for IPv6 - Part 1

When discussing IPv6, it is easy to forget that we are ultimately talking about an enhanced version of an existing network protocol. Sure, it brings about a number of technical advantages. But when viewed in isolation - without a business case - there really are not that many drivers that would place IPv6 on the agenda of the top decision makers looking after budgets. For IPv6 to gain serious momentum, this has to be changed. 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»

IPv4 Market Heats Up While Supply Dwindles

Doug Madory, Director of Internet Analysis at Dyn reports that while the available supply of IPv4 addresses is in sharp decline, the market for these virtual commodities is heating up. In recent months, the pace of the address transfers has greatly accelerated as evidenced by RIPE's table of IPv4 transfers, as well as the increasing number of IPv4 brokers facilitating the exchange of IPv4 address space. 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»

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»

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»

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»

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»

IPv6 for Mobile Networks: Time to Act Now!

Mobile Network Operators (MNOs) serve the largest constituent of connected devices. There are over 4.6B GSM (and its derivatives) subscriptions today. When you add the CDMA family along with technologies with smaller footprints such as WiMax, IDEN to this list, that number tops 5B mark. On the other hand there are only (yes only!) 800M Internet hosts per ISC. Considering such a small percentage of those 5B or so devices are capable of being an Internet host and out of that percentage even a much smaller percentage is connected at a given time, one can understand the sheer potential of explosion in the number of Internet hosts as mobile devices in the next 3-5 years. 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»

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»

IPv6 Backwards Compatibility for IPv4 Most Critical Mistake, Developers Admit

In conjunction with the 74th IETF Meeting, on Tuesday Internet Society held a panel discussion on IPv6 adoption during which Internet engineering community pointed out that the biggest mistake in developing IPv6 is its lack of backwards compatibility with the existing Internet Protocol, IPv4. Reporting today on Network World, Carolyn Duffy Marsan writes: "...leaders of the Internet Engineering Task Force (IETF) admitted that they didn't do a good enough job making sure native IPv6 devices and networks would be able to communicate with their IPv4-only counterparts when they designed the industry standard 13 years ago." ... "IPv6 proponents say the lack of mechanisms for bridging between IPv4 and IPv6 is the single, biggest reason that most ISPs and enterprises haven't deployed IPv6." more»
