Dear colleagues, As you might know, the current IPv6 policy states very clear that assignments to customers must be a minimum of a /64.
5.4.1. Assignment address space size End Users are assigned an End Site assignment from their LIR or ISP. The size of the assignment is a local decision for the LIR or ISP to make, using a minimum value of a /64 (only one subnet is anticipated for the End Site). https://www.ripe.net/publications/docs/ripe-655 On the other hand, a while ago, RFC7608 (BCP198) was published, stating: 2. Recommendation IPv6 implementations MUST conform to the rules specified in Section 5.1 of [RFC4632]. Decision-making processes for forwarding MUST NOT restrict the length of IPv6 prefixes by design. In particular, forwarding processes MUST be designed to process prefixes of any length up to /128, by increments of 1. In practice, this means that the RFC suggests that a customer can get an IPv6 assignment of any size, while the RIPE policy says the minimum should be a /64. I’m interested to know what the community thinks about this and if alignment between this RFC and the RIPE policy is needed. Nathalie Künneke-Trenaman IPv6 Program Manager RIPE NCC
