RIPE NCC::Educa IPv6-only

Next Monday June 8, 2020, 8 years and 2 days after World IPv6 Launch, the RIPE NCC is organizing a RIPE NCC::Educa online education event about running IPv6-only.

Halfway through the morning (European time) I'll be talking about IPv6 address planning, based on my experiences with IPv6 numbering plans (see my publications).

At the end of the event, I'll be participating in a panel discussion with Nico Schottelius and Veronica McKillop titled "When can we turn off IPv4?"

Go to the RIPE website for more information and to sign up.

When it comes to IPv6 adoption, the COVID-19 lockdown means it's Christmas every day!

Back in 2006, Bianca Ryan sang Why Couldn't It Be Christmas Every Day?

Turns out when it comes to IPv6 adoption, it is Christmas every day now:

Google's IPv6 statistics show that during the week, IPv6 adoption is about 5% lower than during the weekends, as apparently, more people have IPv6 at home than at work. Around Christmas, the minimum goes up while the maximum stays about the same.

In this regard the COVID-19 lockdown means it's Christmas every day: between December 20 and January 5, IPv6 adoption didn't drop below 27%. Between January 6 and March 13 there was no work day IPv6 adoption reached 28%, but since March 23, work day IPv6 adoption never dipped below 28%.

Biomassa, dat moeten we nauwelijks willen

Twee weken geleden kwam het Planbureau voor de Leefomgeving (PBL) uit met een rapport over het gebruik van biomassa. Degenen onder ons die gehoopt hadden op een solide doorrekening van het fenomeen en een duidelijke conclusie voor of tegen werden zwaar teleurgesteld. In plaats daarvan werd de noodzaak tot het gebruik van biomassa voor de Nederlandse energievoorziening als uitgangspunt aanvaard, en daarna alleen gekeken of het mogelijk was hierover een polder-consensus te bereiken. (Spoiler: niet dus.)

In een toelichting in het radioprogramma Met het oog op morgen zegt auteur Bart Strengers zelfs (rond 7:25):

Als we de aarde niet meer dan anderhalve graad willen laten opwarmen, hoe gaan we dat dan doen? En als je biomassa uitsluit, dan moet je dat dus doen op andere manieren. Het punt is dat je dan dus heel snel uitkomt op scenario's waarin je zegt dan mogen we niet meer vliegen, dan mogen we geen vlees meer eten...

Alleen gaat biomassa ons op papier wel helpen het doel van maximaal 1,5 graden opwarming te halen, maar in praktijk niet.

RPKI tools and deployment

Recently, Cloudflare launched Is BGP safe yet?. And they immediately answer their own question: No.

What they're getting at is RPKI deployment. RPKI is a mechanism that lets the owner of a block of IP addresses specify which network gets to use those addresses. (Which AS gets to originate a prefix, in BGP speak.) RPKI protects to some forms of (mostly accidental) address hijacking. But for RPKI to work, the address owner needs to publish a "route origination authorization" (ROA) and networks around the globe need to filter based on these ROAs.

Five years ago, I wrote that RPKI is ready for real-world deployment. So where are we now? The US National Institute of Standards and Technology (NIST) has a very nice RPKI deployment monitor, showing the following graph:

Mac Mini 2018/2020 review

Two weeks ago, I ordered a Mac Mini, my first desktop computer in 20 years. This is sort of a review of the Mac Mini, but I reserve the right to digress.

Archiving data: storage prices in 2013 and 2020

Back in 2013, I wrote a blog post about archiving. In it, I compared the costs per terabyte (and the weight per terabyte) of several ways to store data for archival purposes. When I read Beyond Time Machine: 5 Archiving over at The Eclectic Light Company blog, I realized that it’s time revisit this topic.
