这句话关于IPv6指的是哪条规定?

“为此,您需要从 ISP 获取一个 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,它至少需要是一个/64前缀。”

他们指的是哪些规定?(这样,如果我到时候需要为自己辩护,我就能指出一些东西)

答案1

它可能指的是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.
