RIPE NCC Reaching Last /8
• 3 min read
Now we have reached the last /8 of IPv4 addresses, we have looked at the allocation and assignment rate again. At the same time we also monitored the growth in IPv6 allocations.

Update on AS Path Lengths Over Time
• 5 min read
One way to determine the denseness of the Internet, or its “interconnectedness”, is to look at the path length between Autonomous Systems (ASes). A while ago we looked at that and also at differences between IPv4 and IPv6 networks. Has this changed in the meantime? See our findings below.
Update on Assigning 32-bit ASNs
• 3 min read
The RIPE NCC has been assigning 32-bit Autonomous System Numbers since 2007. In this article we're providing an update about the number of 32-bit ASNs being assigned and how many are visible on the Internet.
First Measurement Results from IPv6 Launch
• 3 min read
Like last year during World IPv6 Day, the RIPE NCC has been doing various measurements during World IPv6 Launch on 6 June. We will publish the results in a series of articles on RIPE Labs.
Update on IPv6 Address Distribution
• 5 min read
At the recent RIPE Meeting we presented some IPv6 address distribution statistics which we would like to share with a wider audience. In the article below, you can find statistics on IPv6 allocations and assignments. In particular, the article details what affect the removal of the requirement to b…

... those LIRs that closed. The RIPE NCC now has over 8,000 members. But how many members have closed in the meantime and why?
From 80 to 8,000 - The Growth of the RIPE NCC Membership
• 4 min read
The RIPE NCC is 20 years old and it now has over 8,000 members. In this article, we drill down a bit more into the composition of our membership: what industry do RIPE NCC members come from and which countries account for the highest numbers of members and IP resources.
“Hi Mirjam, have you got any updates by now?”
Hi John, we have published a couple of updates in the meantime. Please see: https://labs.ripe.net/Members/emileaben/has-the-routability-of-longer-than-24-prefixes-changed and https://labs.ripe.net/Members/stephen_strowes/bgp-even-more-specifics-in-2017
“I believe the caption for fig 2 should actually read "Figure 2: Amsterdam power outage on 17 January 2017", not 2014.”
Hi Alison, thanks for pointing this out. You are right. We corrected it in the article.
“I wish to use the dataset of NLANR for my thesis, about analyzing the flow pattern. Would you email me the download link address at hnldtlw@126.com Thank you so much.”
Dear Longwei Tian, Many thanks for your interest in the dataset. Please see the description above. Under Data Users, it is explained how you can access the data. You need to create a RIPE NCC Access account and accept the Terms and Conditions. Please let us know if you have any problems.
“Hiya, great write up...! Feel free to delete this comment once read, but just wondering if you'd consider linking the word "iNOG" in the blogpost to https://inog.net so people can potentially find us to get involved in either day to day, events, or a prospective hackathon as mentioned :) Thanks a mil, Donal @inognet https://inog.net”
Of course. Good idea. Thanks, Donal.
“Hi, my probe #19242 is disconnected to day, after "usb stick dancing" still say disconnected, in SOS messages are this message: BADMD-APP-4780-d41d8cd98f00b204e9800998ecf8427e What's wrong? Thank you David”
Dear David, we will create a support ticket for you and will get back to you by email.
“You're right the right text should be: Let’s suppose a customer provisioned in the first stage with the prefix 2001:db8:1111::/48. Their devices are using, for our example, the first free /64 (2001:db8:1111:1::/64). Everything is fine until there is a power outage. The CPE boots up again when power is recovered, and because the ISP is using a non-persistent prefix, a new prefix is assigned (2001:db8:2222::/48), so now the CPE is announcing 2001:db8:2222:1::/64. However, the devices that have battery (laptops, tablets, smartphones) still have the previous prefix, so now they have two different prefixes (2001:db8:1111:1::/64 and 2001:db8:2222:1::/64). These devices will try to keep using the older one, and they will not work, as the ISP is no longer routing the first prefix to that customer. Just think: if another network failure or power outage were to happen now. Devices could then have three or even more prefixes. And the user will end up calling the ISP help-desk for troubleshooting because the network is not working. Regarding privacy, at the end the best way someone willing to track you has is apps fingerprinting and correlating data, not just addresses. Because the "tracker" can not be sure that it is the same "person" even if the address is the same, it may be several users in the same computer, it may be different computers using the same address at different times, etc.”
This has been replaced in the original text in order to avoid confusion.
“Have to love those early days. RIPE and the RIPE NCC have made a very significant impact on what now seems so normal and common... Wish all of you (us?) a happy 25th birthday!”
Hi Marten, nice to hear from you. Wish you would be here with us to celebrate!
“Hello, Thanks for this informative article. One question: Why does the route6 object explanation contains a v4 example (in the screenshot)? Best regards.”
Hi Raymond, Very good point. We included a different example now. And sorry for the delay - this totally slipped my mind.
“Was using wget --user=****** --password=****** https://data-store.ripe.net/datasets/iplane-traceroutes/2016/traces_2016_08_15.tar.gz downloads ~58kb tar file whereas the file is 836M. Am I doing something wrong?”
Dear Sagnik, it is not possible to use wget with username and password. You need to log in to RIPE NCC Access which will set a cookie, then save the cookie in a file and tell wget to use it. I hope this helpw.
Someone posted a comment here yesterday asking: "Do you have a list of worthwhile testers who might put my surplus credits to good use?" Unfortunately I accidentally deleted this comment so I am re-posting it.
