IAB Response to ICANN Consultation on the Source of Policies & User 
Instructions for Internet Number Resource Requests


The Internet Architecture Board (IAB) is an oversight body of the Internet 
Engineering Task Force (IETF). The IAB provides oversight of the architecture 
for the protocols and procedures used by the Internet. Policies and management 
of IANA functions, including Internet numbering resources, have a broad impact 
on that architecture.

The IP addressing architecture is defined by the IETF. It is documented in the 
RFC series, most notably in RFCs 1122, 1918, 2050, 4291, 5771, and 6890. Note 
that RFC 2050 will soon be replaced by a document that was recently approved by 
the IESG. Global unicast addresses are a single (albeit large) component of the 
architecture. Addresses from this block are allocated to the RIRs. Several 
other address blocks exist, including broadcast, multicast, private address 
space, IPv6 anycast and special purpose address blocks. Allocation and usage of 
addresses in these blocks are specified in the relevant RFCs, including those 
listed above, and are administered in accordance with Section 4 of RFC 2860. 
Parts of address blocks are reserved by the IETF for future use as the Internet 
continues to evolve.

While the solicitation itself notes these address blocks, the draft "User 
Instructions" does not provide any guidance on how these blocks are used or how 
to obtain allocations. Rather it largely limits guidance to unicast IP address 
blocks. We therefore suggest either that the title of the instructions be 
modified to indicate that the instructions are limited to global unicast 
addresses, or that a section be included that discusses these other address 
blocks, referring to appropriate IETF documents, including, but not limited to, 
RFC 5226 (see below) and the relevant RFCs out of those listed above.

RFC 5226 specifies inter alia the means to establish new specialized addresses 
and address blocks that themselves may require different approaches to their 
management. The development of the above listed RFCs over the span of 25 years 
demonstrates that both the needs of Internet users and the capabilities of 
supporting organizations have evolved. It is fair, therefore, to conclude that 
they will continue to evolve.

The IAB looks forward to working with ICANN to further develop user 
instructions, and we are grateful for the opportunity to comment.
