Overall, this document looks good. But a couple of suggestions. As a general comment, I think the document should include a reference wherever it states what a policy is (as defined elswhere). > Reservations of special-purpose AS Numbers are made through Internet > Standards actions. Citation of where that policy is defined? But then later, the document says:: > 3. IANA Considerations > > "IETF Review" as defined in [RFC5226] is required to reserve special- > purpose AS numbers, IPv4 addresses, or IPv6 addresses. Reserved AS > numbers, IPv4 addresses, or IPv6 addresses may be designated to > support testing, IETF experimental activities, or other special uses > (e.g., anycast). These reservations are recorded in the relevant which contradicts the previous statement. Also, would be good to cite all the individual RFCs when restating what the policy is for each registries listed above. > Reservation of special-purpose IPv4 addresses are made through > Internet Standards actions. Reserved IPv4 unicast addresses are > registered in the Special Purpose IP address registries [RFC6890]. Citation for first sentence? > The vast bulk of the IPv6 address space (approximately 7/8ths of the > whole address space) is reserved by the IETF, with the expectation For first sentence, cite where that reservation/delegation was made (i.e., RFC 3513).
