18 years of RIPE and IETF meetings

In the 18 years from 2002 to 2019 I attended 9 RIPE meetings, 1 LACNIC meeting and 16 IETF meetings in 20 cities and 10 countries on 3 continents. Here are a few random photos from each meeting or city.

You may notice camera improvements over time. 😃

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%.

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:
