@elite try to migrate to #IPv6mostly for access networks or start with enabling #IPv6 on services.
What is the router, endpoints make.
Running #IPv6mostly at home. Only Windows, some corp requirements and #IoT and legacy equipment needs a dual-stackl VLAN.
#IPv6mostly
breaking news
(I have to confess apple is sometimes good)
given a #IPv6only mobile access (like the Deutsche Telekom within Germany, not during roaming)
recent apple #iOS 18.5
makes
#IPv6mostly for clients via hotspot
#dhcpoption108 as well #pref64
I made also the windows test - in case option 108 is not provided by the client, iOS provides IPv4
Openwrt ist schon irgendwie genial, auf der einen Seite kann man 464xlat (CLAT) nutzen (in der Paketliste immer ganz oben 🙃) und auf der anderen Seite #ipv6mostly 👍
Das hat bisher nicht mal Android geschafft.
[Перевод] Развёртывание сетей доступа преимущественно на основе IPv6
Изначальной моей задачей было получить сеть на базе протокола IPv6, где клиенты могли по желанию отказаться от использовать IPv4. Задача оказалась не самой тривиальной. В процессе поиска решения наткнулся на очень полезную заметку, которая по сути вобрала в себя всё то, что мне удалось выяснить. Представляю вашему внимаю перевод этой статьи с моими дополнениями по поводу настройки подобной сети на практике. Читать
@stefan @Larvitz running my main wifi and guest wifi since month #ipv6mostly
Family accepted. Only if I take the streaming devices the #IPv4 away, they break.
Home Assistant runs fine IPv6only. Wish that ESPhome could get rid of dual stack as well.
We need proper #IPv6 support in #lwip Anyone knowing how to support this?
@Tubsta Anyone who want to try #IPv6only can just disable IPv4 with any ISP that provides native IPv6. So there is no appetite for such an ISP. It is more the ISPs that reject dual stack and switch to #464xlat and #IPv6mostly
How I feel when dealing with DHCP scope exhaustion, propose the ideal solution, and am forced to drop the DHCPv4 lease time even further.
@goetz @ffhl I needed a while to figure out what practical benefit we would have. One thing that came to my mind: Avoiding #ARP on supporting devices completely if I understand #ipv6mostly correctly. We do have a DHT for ARP in #batman_adv. And could reduce broadcasts a lot with it. But it's still not zero. #IPv6 is so much smarter for Neighbor Discovery as it uses #multicast properly with its solicited mcast addresses and not like broadcasts. And we have #MLD snooping in our #mesh.
A further talk about #ipv6mostly
Be warned the slides move very fastly.😬
Is someone using the combination: #IPv6only / #ipv6mostly network printer + cups, airprint, MacOS?
(Macbook should discover and configure the printer by just a simple "add")
Today I thought about IPv6mostly at work, but I forgot some of my ugly IPv4 dependencies 😢
This draft has now been officially adopted by the v6ops IETF working group and renamed to:
draft-ietf-v6ops-6mops
https://datatracker.ietf.org/doc/draft-ietf-v6ops-6mops/
Also, a related 464XLAT / CLAT draft to keep an eye on:

Hat eigentlich schon irgendeine #Freifunk|gemeinde #ipv6mostly oder #ipv6only dauerhaft im Einsatz?
I opted to test Windows 11 24H2 for my company. Good news, Wi-Fi 7 works great. I’m connected to my U7-Pro at 5.8 Gbps — not that that will get me too far with the AP connected with 2.5GBaseT and 1 Gbps Internet (download, a pathetic 0.035 Gbps upload over DOCSIS). But hey, it looks nice.
Bad news, @jima and @paulos: the promised “future version of Windows 11” with CLAT support isn’t this one. Windows 11 still insists on using legacy IP despite me shoving DHCPv4 option 108 down its throat.

IPB158: “IPv6 Mostly”: A Strategy to Balance Legacy and Modern Networking Needs
Nice changes:
464XLAT-7: If the IPv6 Transition CE Router performs CLAT functions
it SHOULD also include the PLAT prefix in Router Advertisements
([RFC8781]) sent via the LAN interfaces. If the IPv6 Transition CE
Router acts as a DHCP server it SHOULD enable DHCP Option 108
([RFC8925]) processing.

Unfortunately, even Android doesn't do it yet.😭
Alright #DNS64 and #NAT64 finally have been set up on my journey to #IPv6mostly ;c)
How it works: either dual stack or #IPv6only clients ask the DNS server running on my firewall for name resolution; if there exist only IPv4 answers (A records) upstream the DNS64 kicks in and synthesizes IPv6 (#AAAA records) using a special v6 subnet. Then my clients try to connect to those fake v6 addresses and the NAT64 translates v6 back to v4 transparently.
This forces clients to *use* IPv6 only. 🤤
Weil's auf dem denog15 so schön war...
