ipv6 implementation in an ipv4 camp

[Jim Pazarena]

I am curious if anyone can point out articles or deeper instructions
regarding an implementation and launch of ipv6 in a fully ipv4 camp?

If the upstream ISP still provides the end user an ipv4 number
as a gateway, and the end user still has a /24 or /23 assigned by
the ISP, need they be concerned with ipv6?

would the ipv4 /23 subnet be 'translatable' to a corresponding
ipv6 number?

Any source documents would be greatly appreciated.
