Internet-Draft More IPv4 AS112 delegations April 2012
1. Introduction
This is a direction to IANA concerning the delegation of certain
additional IPv4 zones to the AS112 nameservers [RFC6304] which
operates in an anycast cloud [RFC4786].
2. Reverse DNS Delegation, Local-Use and Test Addresses
Work documenting special use addresses [RFC5735] has appeared
containing good candidates for inclusion with the existing
delegations to the AS112 Project. These local and special use
addresses have now been captured and identified for Domain Name
System (DNS [RFC1034] and [RFC1035]) zone administrators to curtail
leaking queries in [RFC6303], in the fine tradition of [RFC1912].
Additionally, [RFC5737] identifies a short listing of IPv4 address
blocks for use in documentation. These too should be considered for
delegation to the AS112 Project.
Thus the purpose of this memo is to effectively signal to the AS112
Project [RFC6304] that it should reflect the efforts of [RFC6303] and
follow directives and delegations subsequently issued as described in
section 6. The ultimate intention is to not create another IANA
resgistry to the already numerous ones that exist.
It is interesting to note that while the focus has largely been on
the use of [RFC1918] addresses, some addresses (such as those first
enumerated within section 4.1 of [RFC1912]) have as of late also been
the subject of [RFC6303] .
3. IAB Considerations
IAB approval of this document is required, consistent with the
guidance provided in [RFC3172].
4. IANA Considerations
As per the provisions of [RFC3172], this document recommends the IAB
to direct IANA to delegate the following reverse DNS zones to the
AS112 nameservers [RFC6304]:

+---------------------------+-----------+---------------------------+
Further, this document recommends the IAB to direct the IANA to
update the Locally Served DNS Zones registry accordingly as per the
provisions of [RFC6303].
AS112 project servers should add these zones to their configuration,
and terminate queries efficiently inside their service
infrastructure. If they are not added, then those servers missing
such zones will appear to be lame to some clients.
This delegation instruction is subject to further direction in the
future from the IAB to IANA, as per the provisions of [RFC3172].
5. Security Considerations
The Security Considerations described in [RFC6304] also apply to
local-use IPv4 addresses, and should be considered in the context of
the use of these addresses.
Security administrators as well as general support personnel who are
involved in the operations of networked devices may also find the
information found in the companion document [RFC6305] quite helpful.
DNS queries may well identify the location of deployment of IPv4
enabled equipment in private contexts, particularly when the reverse
queries relate to local-use IPv4 addresses. While operators of the
DNS reverse servers should respect the privacy of data relating to
individual queries made to these reverse address servers, the
unintentional leakage of information beyond its intended scope of use
and circulation represents a potential threat to the security of a
local private network. This direction to delegate these local-use
IPv4 reverse address sub-domains does not substantially change the
security risks of information leakage from private environments.
