Or, perhaps it is inappropiate for the -bis document to target "Internet Standard" classification at this moment? ¯\_(ツ)_/¯ Especially when solidifying recommendations in an architecture Internet Standard-to-be, the utmost care should be taken to verify whether the paper reality (RFCs) and operational reality (what people do, for $reasons) are aligned. In those years sufficient data has been collected to conclude that /64 is not the "be all and end all". The current paragraph does not account for staticly configured environments in which SLAAC plays no role. Perhaps the following suggestion bridges the gap. ------- OLD: IPv6 unicast routing is based on prefixes of any valid length up to 128 [BCP198]. For example, [RFC6164] standardises 127 bit prefixes on inter-router point-to-point links. However, the Interface ID of all unicast addresses, except those that start with the binary value 000, is required to be 64 bits long. The rationale for the 64 bit boundary in IPv6 addresses can be found in [RFC7421] NEW: IPv6 unicast routing is based on prefixes of any valid length up to 128 [BCP198]. When using [SLAAC], [ILNP], or [NPT66] the Interface ID of unicast addresses is required to be 64 bits long. In other use cases different prefix sizes may be required. For example [RFC6164] standardises 127 bit prefixes on inter-router point-to-point links. For most use cases, prefix lengths of 64 bits is RECOMMENDED, unless there are operational reasons not to do so. OLD: As noted in Section 2.4, all unicast addresses, except those that with the binary value 000, Interface IDs are required to be 64 bits long. NEW: *delete, its superfluous* ------- Kind regards, Job
