@landley @jschauma @ryanc @0xabad1dea yeah, the exhaustion problem would've been shoved back with a #64bit or sufficiently delayed by a 40bit number.

Unless we also hate #NAT and expect every device to have a unique static #IP (which is a #privacy nightmare at best that "#PrivacyExtensions" barely fixed.)

  • I mean they could've also gone the #DECnet approach and use the #EUI48 / #MAC-Address (or #EUI64) as static addressing system, but that would've made #vendors and not #ISPs the powerful forces of allocation. (Similar to how technically the #ICCID dictates #GSM / #4G / #5G access and not the #IMEI unless places like Australia ban imported devices.

I guess using a #128bit address space was inspired by #ZFS doing the same before, as the folks who designed both wanted to design a solution that clearly will outlive them (way harder than COBOL has outlived Grace Hopper)...

If I was @BNetzA I would've mandated #DualStack and banned #CGNAT (or at least the use of CGNAT in #RFC1918 address spaces) as well as #DualStackLite!

#Asia reaches 50% #IPv6 capability and leads world in user numbers
#India and #China deliver a nice milestone, with help from ancient #internet history
It does not, however, mean that more than 50% of devices in #APNIC’s service area – 56 countries that span from Afghanistan to Oceania – rely on IPv6.
Instead, it’s a measure of whether hosts across APNIC’s territory are IPv6-capable, based on an average of the last 30 days of network analysis and probing by APNIC Labs.

The Register · Asia reaches 50 percent IPv6 capability and leads the world in user numbersBy Simon Sharwood

WiFi on German Bahn (DB) ICE trains does still only have legacy IP connectivity in 2025 😠

~ ❯ ip a | grep inet | grep wlp
inet 172.18.155.0/16 brd 172.18.255.255 scope global dynamic noprefixroute wlp2s0

No IPv6. Had to use a VPN tunnel to access the modern internet and help myself with some IPv6.

Huh so currently I have DHCP updating DNS records for each lease it gives out

So question for the ipv6 inclined:

But I've been reading up on SLAAC and stateless dhcp6

Is there a common system to update DNS based on ipv6 records in such a system or would I need to use stateful dhcp6?
