Hi, I'm Iljitsch van Beijnum. These are general neworking-related posts.

Mijn internetsnelheden

In de loop der jaren heb ik een flink aantal verschillende verbindingen naar het internet gehad, en uiteraard werden die steeds sneller. Toen ik ooit die lijn doortrok kwam ik uit op 256 terabit/s wanneer ik met pensioen ga. (De AOW-leeftijd was toen nog 65.)

Tijd om eens te zien of ik inderdaad nog steeds op dat pad zit. Alleen merkte ik dat ik niet echt helder meer had op welk moment ik wat voor lijn met wat voor snelheid had. Tijd voor wat uitzoekwerk dus, en ik zet het hier neer zodat ik het later weer terug kan vinden en kan lachen over hoe sloom alles was in het jaar 2021.

VLANs on the Mikrotik hAP ac³

For my BGP lab/training setups I have a bunch of routers, real or virtual, that each need several IP addresses to talk to other routers. VLANs are the perfect way to keep all of this manageable: with VLANs, it's possible to have separate IP interfaces, but still just use a single Ethernet port to hook everything up. Simple unmanaged switches simply forward the packets to the right port without looking at the VLAN header, so no need to configure the network.

Until I got my Mikrotik hAP ac³ this week...

Ethernet cables in the post-gigabit era

As I'm preparing for the arrival of more > 1000 Mbps Ethernet equipment, I did an inventory of the Ethernet cables I've collected over the years. Turns out there's more variety than expected: I have cat 5 UTP, cat 5e UTP, cat 5e STP and cat 6 STP...

Review: Cable Matters USB 2.5 Gigabit Ethernet adapter

I think it was in 2016 that 2.5 and 5 Gigabit Ethernet was standardized. After a year or two the first USB to 5GE adapters started to appear at about €/$ 100 and about two years ago the first €/$ 50 2.5GE ones. Right now, there's a ton of USB 2.5GE adapters at good prices.

I got a Cable Matters one for € 31 off of Amazon.

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.
