“为此，您需要从您的ISP获取IPv6地址，从技术上讲，这可能是一个
/128前缀（恰好一个IPv6地址），但根据规定，它至less需要一个/64前缀。

他们指的是什么规定？ （所以如果我需要在时间到来的时候保护自己的话，我可以指向一些东西）
它可能是指RFC 6177 。
A key principle for address management is that end sites always be able to obtain a reasonable amount of address space for their actual and planned usage, and over time ranges specified in years rather than just months. In practice, that means at least one /64, and in most cases significantly more. One particular situation that must be avoided is having an end site feel compelled to use IPv6-to-IPv6 Network Address Translation or other burdensome address conservation techniques because it could not get sufficient address space.
