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.

IPv4 nu ook op in Afrika

Met ingang van een paar dagen geleden is IPv4 nu op in alle regio's van de wereld nu AFRINIC, de Regional Internet Registry die Afrika bedient, IPv4 exhaustion phase 2 bereikt heeft.

Zie mijn verhaal De opkomst van IPv6 en ondergang van IPv4 in de jaren 2010 voor meer over het opraken van IPv4 de afgelopen tien jaar.

IPv6 is nu een succes, zelfs bij 25% adoptie

We moeten niet het succes van IPv6 afmeten aan in hoeverre IPv6 IPv4 vervangt, maar in hoeverre IPv6 IPv4 aanvult. En dat doet het al heel aardig op dit moment door IPv4aaS (IPv4 as a service) mogelijk te maken. En IPv4aaS zal ervoor zorgen dat ISPs IPv6 gaan eisen voor peering met streamingdiensten en andere grote contentaanbieders.

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.

→ BGP – the right tool for so many jobs

This is a post that I wrote for the Noction blog:

Like other very successful protocols such as HTTP and DNS, over the years BGP has been given more and more additional jobs to do. In this blog post, we’ll look at the new functionality and new use cases that have been added to BGP over the years. These include various uses of BGP in enterprise networks and data centers.

Recently, I've been looking a bit at BGP in datacenters, and it's really interesting to see how BGP is used in such different ways than it is for global inter-domain routing.

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:
