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. more»

Citrix Case Study Features Nixu DDI

Citrix has published a case study featuring Nixu DDI run on Citrix XenServer by Unify Mobile, a Dutch Mobile Virtual Network Operator (MVNO). Having grown its customer base at an extremely rapid pace, Unify wanted to develop a network services platform that could be scaled up quickly and allow efficient management to cope with growth. more»

Study Reports on Baseline of Global IPv6 Adoption

A new research on native IPv6 traffic across six large providers in North America and Europe suggest that despite fifteen years of IPv6 standards development, vendor releases and advocacy, only a small fraction of the Internet has adopted IPv6. "The slow rate of IPv6 adoption stems from equal parts of technical/design hurdles, lack of economic incentives and general dearth of IPv6 content." more»

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. more»

Asia Pacific IPv4 Exhausted, Becomes First Region Unable to Meet IPv4 Demand

Asia Pacific Network Information Center (APNIC) today announced it has reached the last block of its available pool of IPv4 addresses. The day is marked as key turning point which initiates a major change in regional delegation policy. more»

RIPE NCC Members Secure their Resources Using Certification

Resource certification verifies that an Internet number resource (IP address space or autnonomous system number) has legitimately been allocated by a Regional Internet Registry. It will also benefit every network operator and Internet user in the world by helping to ensure long-term routing stability. more»

Microsoft Offers $7.5 Million to Buy 666,624 IPv4 Addresses

Jaikumar Vijayan reporting in InfoWorld: "Microsoft has agreed to pay $7.5 million to purchase a block of 666,624 IPv4 addresses from bankrupt Canadian telecom equipment maker Nortel in a move that some see as a signal of the increasing value of IPv4 addresses. Last week, Nortel filed a motion seeking approval for the sale from the Bankruptcy Court for the District of Delaware. If the deal is approved, Microsoft would assume control of the IPv4 addresses, currently owned by Nortel, for about $11.25 a piece." more»

2nd Annual RIPE NCC - LEA meeting: Cooperation Unfolds

On Wednesday 16 March the Serious Organised Crime Agency organised a meeting in London with the RIPE NCC. For the second time law enforcers from the whole world met with the RIPE NCC and RIPE community representatives to discuss cooperation. RIPE NCC staged several very interesting presentations that showed the LEAs the importance of the work done within RIPE and ARIN, the information RIPE NCC has and the relevance of all this to LEAs. Also issues were addressed that can potentially be harmful to future investigations. more»

IPv6 Address Allocations

Last year, we presented statistics on the number of RIPE NCC members and the resources distributed to them. Now, one year later, we revisit the topic and look at how things evolved in 2010. We were particularly interested to see how the number of IPv6 allocations increased over time. more»

IPv6 Percolates, IPv4 Regurgitates

APNIC happened to be the first Regional Internet Registry to meet in the IANA post IPv4 era. While discussions and proposals on how to divvy up the last 'slash 8' into tinier blocks are to be expected, it was rather unreal to see the energy spent divining how the RIR's would share IPv4 space that would eventually be returned to IANA and then regurgitated. A timewarp with the exhaustion clock turning backwards? more»

NTIA Request for Comments on the Internet Assigned Numbers Authority (IANA) Functions

On Feb. 25, 2011, the National Telecommunications and Information Administration released the following request for comments concerning the USG's contract for the IANA function. As indicated, the USG's contract for the IANA function with ICANN expires later this year. Interested parties can file comments with NTIA by March 31, 2011. more»

IPv6: The High VoLTEage Telephony Generator

According to IDC, smartphones outsold personal computers, laptops included in Q4 2010! Nokia just announced the demise of the Venerable Symbian in favour of Windows 7 phone and Microsoft's bing search engine! Tectonic shifts are under way to adapt to the rise of wireless broadband, an all IP world, and the growing weight of Apple and Google Android. It is also time to head once again for Barcelona with the Mobile World Congress starting on the 14th. Highlights this year? more»

How a Routing Prefix Travels Through the Internet

What happens when an IP address prefix gets announced or withdrawn. How does this information propagate through the Internet? And how does it affect the amount of Border Gateway Protocol (BGP) traffic across the Internet when a single prefix is freshly announced or withdrawn from the global routing table? The following short analysis shows the detailed effects of these two events. more»

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»
