Vint Cerf: The Launch of a New Larger Internet

In preparation for the World IPv6 Launch tomorrow, Vint Cerf, Chief Internet Evangelist at Google, and a founding father of the Internet, discusses the next version of the Internet, and why we need it.  more»

A Logical Place to Start the IPv6 Transition

The transition to IPv6 is top of mind for most service providers. Even in places where there are still IPv4 addresses to be had surveys we've run suggest v6 is solidly on the priority list. That's not to say everyone has the same strategy. Depending where you are in the world transition options are different -- in places such as APAC where exhaustion is at hand one of the many NAT alternatives will likely be deployed since getting a significant allocation of addresses is not going to happen and other alternatives for obtaining addresses will prove expensive. more»

Business Case for IPv6 - Part 2

In my previous blog on the topic, I stated that the business case supporting the IPv4 roll-out in the late 90s was the Internet. Although IP depletion will slowly become a reality, the chances are that due to mitigating technologies such as NAT and DNS64, it may take quite a while before organizations in the developed economies will get serious about IPv6. So where should we look to find a business case for IPv6? more»

Cel-e-brate v6, Come On!

With IPv6 World Launch coming up it's worth pausing to consider the collective efforts of the Internet industry in enabling and deploying an essential evolutionary technology at what will become truly massive scale. It's easy to be a detractor and believe there has been little progress -- but the Internet hasn't melted down and there is no evidence it is about to. Perhaps the issue is that progress occurred in a different way than was predicted or preferred by the experts. more»

Measuring IPv6 at the Network and the Customer Level

George Michaelson, APNIC's Senior Research and Development Scientist recently visited the RIPE NCC to collaborate on various research projects with his RIR colleagues. IPv6 measurements were one of the topics we looked at. Recent IPv6 statistics from the RIPE NCC show an accelerated uptake of IPv6 in Norway, both in terms of the number of allocated prefixes, and visible announcements in the routing system. 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»

From 80 to 8,000 - The Growth of the RIPE NCC Membership

The RIPE NCC is 20 years old and it now has over 8,000 members. In this article we are looking at the growth curve and the composition of the membership: what industry do RIPE NCC members come from today. The RIPE NCC became the first Regional Internet Registry in September 1992 (six months after it was set up as the secretariat for the European operators community, RIPE). more»

Number Misuse, Telecommunications Regulations and WCIT

Another twenty five years has just zoomed by, and before you know it, it's all on again. The last time the global communications sector did this was at the WATTC in 1988, when "the Internet" was just a relatively obscure experiment in protocol engineering for data communications. At that time the Rather Grand telephone industry bought their respective government representatives... to the Rather Grandly titled "World Administrative Telegraph and Telephone Conference (WATTC) in November 1988 in Melbourne, Australia and resolved to agree to the Rather Grandly titled "International Telecommunication Regulations." more»

Department of Commerce Cancels IANA Contract RFP

The United States government has cancelled IANA Request for Proposal (RFP) SA1301-12-RP-IANA according to an updated page made today on the FedBizOpps website. The change -- time stamped Mar 09, 2012 2:44 pm -- states: "The Department of Commerce intends to reissue the RFP at a future date, date to be determined (TBD). Interested parties are encouraged to periodically visit www.fbo.gov for updates." more»

No Big Run on IPv4 in 2011

2011 was an interesting year for IPv4: in February 2011, the Internet Assigned Numbers Authority (IANA) handed out their last free IPv4 address blocks to the Regional Internet Registries (RIRs). In April 2011, the APNIC (the Regional Internet Registry for the Asia Pacific region) started allocating from its last /8. At the RIPE NCC we did not see a big jump in IPv4 address allocations in 2011, as anticipated by some observers. more»

Data Quality in the RIPE NCC Service Region

In an earlier article on CircleID, Registry Data Quality Assessment, we discussed the importance of high quality and accurate IP registry data. At that time, we focused mainly on the accuracy of legacy address space: IP addresses that were given out prior to the existence of the RIPE NCC and that are not part of the current registry system. In this article, we want to present the efforts to keep the address space that is the responsibility of the RIPE NCC up to date and well maintained. more»

DDI Integration: We Need IPAM

I am a big fan of DDI (DNS, DHCP and IPAM) as magical trio to manage all transactions on network infrastructures... Or to say the least: make it possible. Basically it makes these "Core Network Services" concise, manageable and integrated. It basically makes the network infrastructures of today and the future possible. There is however one thing that continuously seems to irritate when talking about integrating these services on networks. more»

IP Address Space Covered by Certificates

Since the RIPE NCC launched its Resource Certification service, there is a steady increase in the number of prefixes covered by certificates. The Resource Certification (RPKI) service was launched at the beginning of 2011. The system enables network operators to perform Border Gateway Protocol (BGP) origin validation, which means that they can securely verify if a BGP route announcement has been authorised by the legitimate holder of the address block. more»

DNS Measurements with RIPE Atlas Data

As described in New RIPE Atlas Features in the Making, each RIPE Atlas probe performs "anycast instance discovery" measurements. This means, for each DNS root name server, we determine which instance of a name server a probe uses. We compile the data from all probes and build maps showing these results for each Atlas probe. In other words, the map shows the "gravitational radius" for root DNS server instances. more»
