Recent Enhancements to ARIN's whoIS-RWS Service

ARIN deployed a series of enhancements to its Whois-RWS service today. This includes enabling CIDR support and IPv6 lookups in the search box on the web page, provided plain text rendering of lists of ASNs and networks on the web - plus enhanced CIDR query matching on WHOIS port 43. more

The Central IPv4 Pool is Gone

Yesterday, the Asia-Pacific registry got the last two blocks in the central IPv4 pool. The IANA has been sitting on five /8s (one per regional registry), and these will be handed out (along with the fragments from the legacy class B space), one to each registry. The IANA IPv4 registry doesn't yet reflect this. more

Global Patterns in IPv4 Allocation Statistics

In January 2007 we highlighted that the IPv4 allocation rate had increased significantly since early 2004. By 2006 it was clear that continued growth would see IPv4 exhaustion occur sometime between 2010 and 2015. In October 2010 we revisited the subject in the CircleID articled 'Graph Shows Decline of IPv4 Almost Linear'. ... Now, in January 2011, we are very close to the exhaustion of the IANA pool of IPv4 address space. more

The ISP Industry and the Financial Sector - Amazing Similarities

In the last RIPE Labs article on this subject How Does the Internet Industry Compare?, we looked at ways to compare our industry with other industrial sectors, and identified a number of characteristics that an industry must have in order to be comparable to the Internet industry. It seems the financial sector or monetary credit industry shares many of these characteristics and in fact behaves much like the Internet industry. more

Addressing 2010

It's January again, and being the start of another year, it's as good a time as any to look at the last 12 months and see what the Internet was up to in 2010. This is an update to the report prepared 12 months ago when looking at 2009, so lets see what has changed in the past 12 months in addressing the Internet, and look at how address allocation information can inform us of the changing nature of the network itself. more

How Accurate is the Routing Registry?

The Internet Routing Registry (IRR) is a globally distributed routing information database that consists of several databases run by various organisations. Network operators use the IRR to publish their routing policies and routing announcements in a way that allows other network operators to make use of the data. In addition to making Internet topology visible, the IRR is used by network operators to look up peering agreements, determine optimal policies and to configure their routers. more

How Does the Internet Industry Compare?

In an earlier CircleID post (The ISP Industry: Concentrated or Diverse?) we discussed if the ISP industry is concentrated and concluded the industry is amazingly open and varied. This time we try to identify criteria that make other economic sectors comparable to our own industry, using the global automotive manufacturing sector as an example to test our assumptions. Comparing the Internet industry with other industries is interesting, because it is quite special in a number of ways: it is transparent, keeps detailed records and values a high level of industry self-regulation. It also enables organisations to serve a global market. more

How Complete is the RIPE Routing Registry?

The Internet Routing Registry (IRR) is a globally distributed routing information database. The IRR consists of several databases run by various organisations in which network operators can publish their routing policies and their routing announcements in a way that allows other network operators to make use of the data. In addition to making Internet topology visible, the IRR is used by network operators to look up peering agreements, determine optimal policies and, more recently, to configure their routers. 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

ARIN Recognizes Interop for Returning IPv4 Address Space

ARIN today recognizes Interop, an organization with a long-standing presence in the Internet industry, for returning its unneeded Internet Protocol version 4 (IPv4) address space. Interop was originally allocated a /8 before ARIN's existence and the availability of smaller-sized address blocks. The organization recently realized it was only using a small portion of its address block and that returning the remainder to ARIN would be for the greater good of the Internet community. more

Vinton Cerf Elected and Paul Vixie Re-elected to the ARIN Board of Trustees

Vinton Cerf has been elected and Paul Vixie has been re-elected to the ARIN Board of Trustees. Each will serve a three-year term commencing 1 January 2011. The ARIN Board of Trustees congratulates Vinton and Paul. The Board thanks Aaron Hughes and Lee Howard for their participation as candidates in the election and encourages their continued participation in the ARIN community. The Board would also like to thank Lee Howard for his service and contributions during his tenure on the Board. more

IPv4 Address Space Now Below 5%, Says NRO

The Number Resource Organization (NRO) announced today that less than five percent of the world's IPv4 addresses remain unallocated. APNIC, the Regional Internet Registry for the Asia Pacific region, has been assigned two blocks of IPv4 addresses by the Internet Assigned Numbers Authority (IANA). This latest allocation means that the IPv4 free pool dipped below 10% in January, just nine months ago. Since then, over 200 million IPv4 addresses have been allocated from IANA to the Regional Internet Registries (RIRs). more

IPv6 Momentum?

Last month, the Obama administration sponsored one of the first high-level government workshops on IPv6. At the meeting, the administration's Chief Information Officer, Vivek Kundra, announced a remarkable 2012 deadline for federal agencies to support IPv6. So with a high-level US government mandate and a recent spade of vendor and carrier IPv6 announcements (e.g. VeriSign, Hurricane Electric), is the 15 year old IPv6 migration effort finally gaining momentum? more

IPv6 and the Fear of Brokenness

Brokenness refers to the situation whereby a website is made accessible in dual stack, meaning both IPv4 and IP6, using records referred to as A's for IPv4 and quad A's for IPv6. Some end-users can experience slower access to the website or in some rarer instances no access at all. Brokenness is mostly attributable to older versions of the Mac Os operating system... The brokenness issue has been very well described by Eric Vyncke... 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
