Just obsessing over this:

In the ULA RFC and postings, people always use the fc00:: prefix as an example, it seems. But according to RFC 4193, the 8th bit in the first octet must be set to 1, to indicate "local," at least until someone figures out how to use a non-local ULA scheme.

So in fact, the first octet will always be fd, yes?

Just obsessing on a Good Friday.

Thanks.
