Hi, I'm Iljitsch van Beijnum. Here on iljitsch.com I publish articles and post links about a range of topics.

Also have a look at my business web site inet⁶ consult.

→ Film processing chemistry, how does it work?

If you want to understand the chemical reactions at work during the processing of a film without going back to your school bench:

Will the IPv6 BGP table overtake the IPv4 table before the decade is out?

For my training courses, I always check the current size of the IPv4 and IPv6 BGP tables over at the CIDR Report so I can tell the participants what table size capacity to look for when shopping for routers.

Currently, the IPv4 table is at 925k, readying itself for scaling the 1M summit late next year. The IPv6 table is 160k prefixes.

The IPv4 table grew at about 10% per year in the 2010s and 6% last year. At this rate, it'll be at 1.43 million at the beginning of 2030.

The IPv6 table, on the other hand, had been growing at some 31% per year between 2015 and 2020, but last year it grew 37%. At that rate, the IPv6 table will reach 1.7 million prefixes by 2030! Even at a somewhat slower growth rate of 34% the IPv6 table will overtake the IPv4 table before the decade is out.

Of course it's hard to predict 7.5 years into the future, but stranger things have happened.

Also, at this rate, you'll need a router that can handle more than 2 million prefixes five years from now. Which pretty much means that if you are buying a router today that has to be able to hold the full global IPv4 and IPv6 tables, it should already be able to handle more than 2M prefixes in order to have a five year economic lifespan.

Shooting film

In this digital age, we still may want to shoot photos on film. But what type of film?

Or why film in the first place?

I think that last question will have a different answer for everyone. For me, it's the joy of seeing decades old machines do what they were built to do so cleanly. I can just pull the film advance lever and push the shutter on my Nikon FE time and time again, it never gets old. It's even better when there's film in the camera. Although of course then this starts to cost real money.

6-6-2012: World IPv6 Launch — the future is forever

Ten years ago, on 6 June 2012, the Internet Society organized World IPv6 Launch. A year earlier, we'd had World IPv6 Day, where many (large) organizations added IPv6 addresses for their websites to the DNS for 24 hours, in order to see if that would create problems. That went mostly smoothly, with a few surprises, so a year later it was time to turn on IPv6 for real. Time for a blog post looking back on worldipv6launch.org.

I thought this would be a good excuse to do what I've done with some regularity over the years: see how well things work when I turn off IPv4 on my home network.

Review: A500 Mini, F710 game controller, PETSCII Robots

The A500 Mini, the Logitech F710 and Attack of the PETSCII Robots: an excellent combination. So let me cover all three in a single review.
