But I think a host should be > allowed to assume that its own subnet and its own IID are 64 bits > long. Such an assumption would fundamentally break SIIT [RFC7915]. Consider the following examples of IPv4-translatable IPv6 addresses [RFC6052] that might be assigned to hosts on different links in a vanilla SIIT (a.k.a. IVI) deployment: 1) 2001:db8::192.0.2.1/120 2) 2001:db8::198.51.100.1/120 3) 2001:db8::203.0.113.0/120 These are all in the same /64 but if these tree hosts assume the /120 prefix length is incorrect and "helpfully correct" it to /64, then they can no longer communicate with each other. Thus, if you want to give the host permission to make such an assumption of /64, you'd need to make exceptions for IPv4-translatable IPv6 addresses (or deprecate RFC7915 and possibly RFC6052). However, creating such an exception probably means in practise that implementations much apply it to the entire IPv6 address space, because there is no way for a host to determine whether or not, e.g., 2001:db8::c000:201 (host #1 above) is an IPv4-translatable IPv6 address or not (that I'm aware of, anyway).
