       @noipv6https://nitter.net/noIPv6/status/1696046404173471851#mIPv6-only and IPv6-mostly are not identicalIPv6-mostly contains a part for IPv4 self destruction But that part works only on LAN and WiFi.On 4G/5G environments IPv6-mostly is irrelevant.IPv6-only is sufficient.

       @tschaefer there’s nat64, so i’m not sure your point? 🤔

       @noipv6 The difference between ipv6-only and ipv6-mostly is the possibility to suppress ipv4 addresses via dhcpv4. The IPv6 part is identical.  4G/5G have a different method for assigning IPv6/IPv4 addresses - usually there is no dhcpv4 client endless requesting ipv4 addresses.

       @noipv6 Ok, the RA-option is new on the ipv6 part. But in my in opinion - a nice to have feature. Not more.(saying in one protocol don't look for the other one)

       @tschaefer the fixed wireless side of that “100 million user” example uses 464xlat, so clatd, so… 🤷🏻

       @noipv6 About which "fixed wireless" do you speak?Of course ipv6-only and ipv6-mostly use 464xlat, clatd ....But the difference between is:ipv6-only - you just don't provide dhcpv4ipv6-mostly - asks the clients if dhcpv4(ipv4-address) is neededipv6-mostly is a minimal (in my opinion overdeveloped) extension to ipv6-only The statement/Question was:IPv6-mostly is supported by almost all mobiles devices, but not on server side - who is using it on server side?

       @noipv6 ipv6-mostly runs dualstack and ipv6-only in parallelin best case all devices opt out of ipv4 and dhcp(v4)traffic is quit low

       @tschaefer where exactly was “server side” stipulated? 🤨

       @noipv6 Does anyone actually use #IPv6-Mostly? It seems to be well supported on the client side, but you won't find much about it on the Internet.Together with the mentioned ripe blog - the questions asks for server examples - since dhcp option 108 and the RA options are not widely implemented (on server side).If you don't use these options, ipv6-only (and 464xlat/clat) will still work. If you see 192.0.0.4 on your device, cannot distinguish if it's as result of ipv6-only or ipv6-mostly.

       @noipv6 you have to sniff the network.

       @tschaefer a) i still don’t see how that blurb inherently says anything about server-side; i read it as “client-side SUPPORT exists, clearly, but who’s actually IMPLEMENTED it?”& b) maybe a “duh” take on my part, but i hadn’t seen “ipv6-mostly” as intrinsically linked w/ dhcpv4 option 104, interpreting it more as a generic acquiescence of the whiners’ age-old outcry of “it’s OBVIOUSLY not an ‘#ipv6-only network’ if you still provide connectivity to [legacy ip] networks 🥴”

       @noipv6 Android, iOS, MacOS support IPv6-mostly. (Windows, Linux (Network-Manager)) doesn't.As long you don't change the clients - it's a question how the (server) network is configured. I have it only seen once. It was during the last RIPE meeting. In IPv6 mostly networks dhcpv4 server und dhcpv4 clients negotiate not to assign IPv4 addresses. (except clat, but that a part of 464xlat)
