IPv4 Markets

A Look Inside the Emerging Private IPv4 Market

A significant quantity of unused, previously allocated IPv4 addresses are becoming readily available for re-distribution to IP network operators in need of the depleted addresses. Network World has published a report that takes a look at this emerging private market that's allowing companies with excess numbers to sell them to those in need. more

Scarcity of IPv4 Addresses

My friend Kurtis writes in his blog some points he has been thinking of while discussing "when we run out of IPv4 addresses". In reality, as he points out so well, we will not run out. It will be harder to get addresses. It is also the case that unfortunately people that push for IPv6 claim IPv6 will solve all different kinds of problem. Possibly also the starvation problems in the world... more

IPv6 Deployment: A Very Complex Time Bomb with an Uncertain Trigger Date

I did a 2 hour interview on October 23rd with John Curran, Board Chair of ARIN the North American Regional Internet Routing Registry for the last decade. I now understand what is at stake with IPv6. Outside of a key core group of network engineers I think darn few people do understand. And not all of them agree on how the scenario plays out though virtually all say the situation is very serious. John believes that it is huge. It is as big as Y2K except no one knows a precise date by which everything has to be done... more

Defense Department Demonstrates Compliance with the OMB IPv6 Mandate

IPv6 is "critical to achieve our net-centric vision", said Kris Strance, DoD Lead for IP Policy, speaking at the Information Assurance Collaboration Forum (IACF) in Laurel, Maryland last week. The Defense Department sees the proliferation of IP-addressable devices as a key driver for IPv6 adoption, and does not believe that IPv4 can satisfy its future requirements. The imminent explosion of non-traditional IP-enabled devices that Defense intends to implement may even threaten the large IPv4 address allocations that the Department holds. more

The IPv4 Market - 2018 Mid-Year Report

The number of IPv4 transactions and volume of IP addresses flowing to and from organizations in the ARIN region in the last 6 months put 2018 on track to be the most active year in the history of the IPv4 market. Nearly 25 million numbers were transferred in the first half of this year, more than doubling the volume of numbers transferred by this time last year and continuing the level of market activity in the last half of 2017 when just over 28 million numbers were transferred. more

RIPE NCC Distributed Last IPv4 Address Space from the Available Pool

On Friday 14 September, 2012, the RIPE NCC, the Regional Internet Registry (RIR) for Europe, the Middle East and parts of Central Asia, distributed the last blocks of IPv4 address space from the available pool. more

NTIA Holding Workshop on IPv6

The National Telecommunications and Information Administration (NTIA) is hosting a workshop today discussing the state of IPv6 in the U.S. and its impact on the industry, government, and the Internet economy. The moderators for the workshop are Aneesh Chopra, Chief Technology Officer of the United States and Vivek Kundra, Chief Information Officer of the United States. Participants include... more

The Trouble With 6to4

In the transition from IPv4 to IPv6, the preferred solution for network endpoints is to have both native IPv4 and IPv6 connectivity (also called dual-stack connectivity). If a site cannot get native IPv6 connectivity, however, the IPv4 network endpoints can choose from a number of conversion technologies to connect to the IPv6 Internet. The most commonly used conversion mechanisms are 6to4, Teredo and tunnel-brokers. At recent RIPE meetings there have been claims that 6to4 connectivity is quite often broken. We were interested to find out how broken it really is. more

As IPv6 Deploys, Will We Look Back on NAT as the Ugly Step Sister or Unsung Hero?

The debates are raging over whether or not we should migrate to IPv6. The strongest argument is the enormous address space that will allow for everyone and everything to have a unique public address, many addresses actually. It is often said that the shortage of public IPv4 addresses has limited our capabilities because it led to the pervasive use of private addressing, Network Address Translation (NAT) and Port Address Translation (PAT). Though these technologies remain critical, they are often regarded as stop-gap measures, and they sometimes create problems. In some circles, NAT has acquired a very bad name. But is that a fair perspective of the technology? Let's review the positives and negatives. more

Simple Overview of ICANN and the IANA Transition by Vint Cerf

Google has released a Doodle Video Animation of its VP and Chief Internet Evangelist, Vint Cerf, explaining inner workings of the Internet, formation of ICANN and the IANA transition. more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

A story... ZZZ Telemarketing (not a real name) is locked in a heated fight with their bitter rival, YYY Telemarketing (also not a real name), to win a very large lead generation contract with Customer X. Customer X has decided to run a test pitting the two companies against each other for a week to see who can generate the most leads. The ZZZ CEO has said to his staff that it is "do or die" for the company. If they fail to win the contract, they will have to shut down -- they need to do "whatever it takes" to win over YYY. A ZZZ staffer discovers that part of why YYY has consistently underbid them is because they are using SIP trunks to reduce their PSTN connection costs. But the staffer also discovers that YYY is using very cheap voice service providers who run over the public Internet with no security... more

Pentagon Gave Control of 175M Dormant IP Addresses to Florida Company Right Before Trump’s Departure

The US Department of Defense gave a small unknown Florida company control to millions of its dormant IP addresses, minutes before President Trump left office. According to reports, the unknown Florida company, Global Resource Systems LLC, initially obtained control of 56 million Pentagon-owned IP addresses on January 20 and later increased to near 175 million IP addresses. more

How Failure To Maintain IPv6 Is Hindering Law Enforcement

Recently, the FBI, DEA and even the Canadian Mounted Police have suggested that the switch to IPv6 is making it more difficult to track criminals online, those who would traffic in things such as drugs or child pornography, in addition to hackers, botnets, kidnappers and terrorists. Under IPv4, it wasn't very difficult to find offenders online via their IP addresses. The American Registry of Internet Numbers (ARIN) would hand out the address and internet providers would log them into the public WHOIS database. 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

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more
