Dear colleagues

Version 2 of prop-110: Designate 1.2.3.0/24 as Anycast to support DNS
Infrastructure, reached consensus at the APNIC 37 Policy SIG, but did
not reach consensus at the APNIC 37 Member Meeting.

Therefore, this proposal is being returned to the authors and the Policy
SIG mailing list for further consideration.

Proposal details
----------------

The objective of this proposal is to permit the use 1.2.3.0/24 as
anycast addresses to be used in context of scoped routing to support the
deployment of DNS resolvers.

Proposal details including the full text of the proposal, history, and
links to mailing list discussions are available at:

1. Problem statement
--------------------

   Network 1 (1.0.0.0/8) was allocated to APNIC by the IANA on 19
   January 2010. In line with standard practice APNIC's Resource Quality
   Assurance activities determined that 95% of the address space would
   be suitable for delegation as it was found to be relatively free of
   unwanted traffic [1].

   Testing, conducted by APNIC R&D found that certain blocks within
   Network 1 attract significant amounts of unwanted traffic, primarily
   due to its unauthorised use as private address space [2].

   Analysis revealed that, prior to any delegations being made from the
   block, 1.0.0.0/8 attracted an average of 140Mbps - 160Mbps of
   unsolicited incoming traffic as a continuous sustained traffic level,
   with peak bursts of over 800Mbps.

   The analysis highlighted individual addresses such as 1.2.3.4 with
   its covering /24 (identified as 1.2.3.0/24) remain in APNIC
   quarantine and it is believed they will not be suitable for normal
   address distribution.

   The proposal proposes the use of 1.2.3.0/24 in a context of locally
   scoped infrastructure support for DNS resolvers.

2. Objective of policy change
-----------------------------

   As the addresses attract extremely high levels of unsolicited
   incoming traffic, the block has been withheld from allocation and
   periodically checked to determine if the incoming traffic profile has
   altered. None has been observed to date. After four years, it now
   seems unlikely there will ever be any change in the incoming traffic
   profile.

   The objective of this proposal is to permit the use 1.2.3.0/24 as a
   anycast addresses to be used in context of scoped routing to support
   the deployment of DNS resolvers. It is
