I was one of the co-authors for AFPUB-2012-V4-001 (Anycast assignments)
It has been strongly suggested to me that the current proposal be
extended to include both IPv6 and ASN resources as well.
1) Summary of the Problem Being Addressed by this Policy Proposal
The current policy (AFPUB-2012-V4-001) that lets AFRINIC members
acquire space for anycast service deployment purposes does not
provide the ability to request IPv6 anycast space (and for AFRINIC
to issue it to anyone). There's also no provision for issuing AS
Numbers for anycast purposes. This proposal attempts to modify
AFPUB-2012-V4-001 to fix these issues.
2) Summary of How this Proposal Addresses the Problem
The proposal modifies AFPUB-2012-V4-001 to include the option to
request IPv6 space and AS Numbers for anycast purposes from AFRINIC
and for AFRINIC to issue these resources to the requestors.
For the avoidance of doubt, the author does not seek to prolong the
lifespan of IPv4 with this proposal but rather, to ensure that
number resources allocated/assigned by AFRINIC are used by
legitimate members from the service region to support their network
operations, regardless of physical location.
AFPUB-2012-V4-001 is modified from the original version to the
1. Summary of the problem being addressed by the policy proposal
This proposal allows an organization to receive an IPv4/IPv6
allocation or assignment and an AS Number purely for anycast or GPRS
Roaming Exchange (GRX) usage.
2. Summary of how this proposal addresses the problem
This proposal allows the use of:
a. One (1) /24 of IPv4 for anycast services from a PA allocation of
an LIR or direct end-user assignment.
b. One /48 of IPv6 for anycast services from an IPv6 LIR allocation
or direct end-user assignment.
c. An AS Number for anycast purposes.
AFRINIC staff will consider anycast IPv4/IPv6 blocks assigned to be
"fully utilised" by the LIR when considering utilisation for first
allocation or for an additional allocation to an LIR.
3.1 An organization may obtain one (1) /24 IPv4 and/or one (1) /48
IPv6 prefix for anycast or GRX purposes from an allocation or an
AFRINIC issued direct end-user assignment. An AS Number should also
be issued for the same purposes if requested. These resources must
be used for the sole purpose of anycasting web or authoritative DNS
servers as described in BCP126/RFC 4786
(http://www.ietf.org/rfc/rfc4786.txt) or for GPRS Roaming Exchange.
The IPv4/IPv6 prefixes will count as being fully utilised when an
organization applies for additional resources. The utilization
criteria that apply to all IPv4 and IPv6 initial allocation or
assignment requests shall be waived for anycast assignment requests.
3.2 Blocks used for anycast services cannot be further assigned or
sub-allocated. They shall be tagged with the status attribute in the
AFRINIC whois service as "ASSIGNED ANYCAST".
