> So if I have 1000 devices I have to advertise every single one to my ISP?
Generally: No, if they use Prefix Delegation (which is what most non-mobile ISPs use). Your router sends a DHCPv6-PD request and the ISP delegates a /48 (usually) or /64 (if they are run by morons) prefix to your router. Your router advertises that prefix on the local network, and hosts self-assign addresses within that prefix.

Most OSes generate new random addresses every 24 hours (and keep old addresses with open connections), so there is no reliable way for your ISP to determine how many hosts are on your network.
