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

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

Logging in on my Mac using a VT420 terminal

At my first job back in 1992 I had three things on my desk: a big phone, a 486SX PC running Windows 3.0 and a DEC VT320 terminal. Even back then those were pretty outdated, but we still used them for our helpdesk ticket system and our in-company email. (By the way, I recommend that everyone in tech starts as a helpdesker.) Five years later, I started a company with four others, and the first business we did was collect a bunch of VT420 terminals, which we then sold for ƒ 25,- a piece. I kept one for myself.

So the Digital VT100 terminal family holds a special place in the retro tech corner of my heart. Over the years, I tried to connect the terminal to my Mac using a USB-to-serial converter a few times, but never got anywhere. Today, I tried again, and finally got everything to work.

Winner doesn't take all: IPv6 is now a success, even at 25% deployment

We shouldn't gauge the success of IPv6 by looking at how much IPv6 replaces IPv4, but by how much IPv6 complements IPv4. And it's already doing that quite well today by making IPv4aaS (IPv4 as a service) possible. And IPv4aaS will make ISPs require IPv6 when peering with streaming services and other big content providers.

IPv4 now also exhausted in Africa

As of a few days ago, IPv4 has run out in all regions in the world, as AFRINIC, the Regional Internet Registry that serves Africa, has now reached IPv4 exhaustion phase 2.

For more on the IPv4 exhaustion over the last decade, see my story The rise of IPv6 and fall of IPv4 in the 2010s.

IPv6 and the DNS: missed opportunities

A few days ago I ran into this blog post from 2012: Deprecate, Deprecate, Deprecate, which lists a bunch of IPv6 stuff that's been "deprecated" by the IETF. That means: we changed our minds about this protocol or feature, stop using it.

The rise of IPv6 and fall of IPv4 in the 2010s

The 2010s were the decade that we ran out of IPv4 addresses and the decade that IPv6 deployment got underway—but IPv4 is still going strong even without a fresh supply of addresses.

Here's an overview of what happened with IPv4 and IPv6 in the 2010s.

Mijn nieuwe bedrijfsnaam: inet⁶ consult

Vandaag is voor mij een bijzondere dag. Precies 20 jaar geleden ging ik op de eerste werkdag van het nieuwe millennium naar de Kamer van Koophandel om mij in te schrijven als eenmanszaak.

Met een paar kleine zijpaden richting Madrid en het ministerie van BZK is dit nog steeds het pad wat ik volg. Alleen is er één ding wat ik 20 jaar geleden niet zo goed gedaan heb: de keuze van mijn bedrijfsnaam.

Ik dacht: ik kies iets wat niet bestaat, dat is uniek en associëren mensen dus automatisch met mij. Aldus: Muada. Maar dat leidde alleen maar tot steeds uitleggen dat het toch echt niks betekent.

Vandaag is het dan zover: ik herlanceer mijn bedrijf met een nieuwe bedrijfsnaam en een nieuwe website. De naam is inet⁶ consult.

Als in: Iljitsch NETwerk CONSULTancy. En natuurlijk staat "inet" voor het internet. Alleen was al weg. Dus: inet⁶ consult. inet6 is natuurlijk kort voor IPv6, niet geheel ontoepasselijk. Ook wil ik me focussen op zes onderwerpen:

Natuurlijk staat dit alles uitgelegd op de nieuwe website:
