Why? The purpose of reserving a prefix for documentation is to ensure that documentation prefixes doesn't clash with ones assigned by a registries. For locally assigned ULA don't need a reserved prefix because there is no registry assignments to clash with. For centrally assigned ULA there is no registry yet so no practical examples can exist. When such a registry is assigned we can document a prefix in the meantime just generate a new prefix when you write your documentation. dd if=/dev/random bs=5 count=1 | od -tx1 | awk '/000000/ { print "fd" $2 ":" $3 $4 ":" $5 $6 ; exit} Or flip a coin 40 times.
