You tell major ISPs: the IPv6 blocks they got are mainly for the ISP
clients, and only secondarily for themselves :-)

It worked for me :-)

(basically, when an ISP asks for an IPv6 block to RIR, the RIR asks back
how many clients they have, and subsequently they dimension the size of
these IPv6 blocks; so the ISPs are bound to this).
