ah gods damn it Android implements DHCPv6 now but won't even try to use it without the P flag set even though "the absence of any PIOs with the P bit does not carry any kind of signal to the opposite and MUST NOT be processed to mean that DHCPv6-PD is absent" RFC 9762

@dysfun @q it does implement it correctly. That is worded as a negative. Android isn't disabling its DHCPv6-PD, it's _not enabling_ it.
That sentence was written for CPEs, to avoid people going oh this applies to ISP uplinks, let's break everything there.
(PS: check the author names on that RFC)

@equinox @dysfun ok maybe some slightly unclear wording then 😉
I should go direct my annoyance at JunOS for not letting me set that flag then
