    in ipv4 if we are assinged one public ip by our isp we can give access to a whole bunch of computers (and other devices) access to public internet throug NAT .

    now in ipv6 there is no NAT ..

    so what if we were given one ipv6 address by our isp .. how would we allow a bunch of ipv6 devices to share that one ip for internet access ?
    what is performing the translation ?

    I think it's a long way away from ISPs dishing out IPv6 addresses. But I think it's more a point that with IPv6 NAT isn't necessary due to the volume of addresses available, not that there is no provision for NAT at all.

    You generally get a prefix assigned by your ISP, not an IP address in itself.
    For example, I get a /56 prefix assigned by my provider. The router then either assigns itself an IP address using EUI-64, or you can set one yourself.
