And if IANA didn’t understand the instructions they had a opportunity during the RFC creation process to request clarification. It is a explicit step in the process to try to prevent issues like this. IANA could have done the delegation at that point in time and had it in place before the RFC exited the RFC publication process and even asked “Is this correct?”. IANA make similar queries for registry entries. Creating a delegation is a operation that happens millions to times a day around the world as is setting up name servers to serve a zone. As for “point to” read it as “delegated to” if you want to nit pick. Also IANA was NOT instructed to delegate to the AS112 servers. IANA was instructed to delegate to back hole servers and a example of which, the AS112 servers, was presented.
