As a service provider, the minimum prefix you can get from AFRINIC is a /32 Provider Aggregatable prefix.
The current policy makes it mandatory for LIR members to announce an IPv6 PA allocation within 12 months and, to the extent practicable, as a single aggregated prefix, so as to minimize global routing table growth.
In some very special cases, space may not be announced, however, it must be duly justified by the member to AFRINIC.
As an End-User organisation, the minimum prefix you can get from AFRINIC is a /48 Provider Independent prefix.
The organization must deploy the IPv6 provider-independent address space at each end-site, for which addresses are obtained, within twelve (12) months.
If the addressing space justification was that it will be announced, to the extent practicable, the organization should aggregate any announcements of prefixes so as to minimize global routing table growth.
A nibble is 4 bits. A nibble boundary is a network mask that aligns with a boundary of 4 bits. The size of the IPv6 prefix to be delegated should match a nibble-aligned boundary to keep addressing plans easily readable and understandable. Moreover, since DNS reverse delegations for IPv6 are based on the closest 4-bit boundaries, the use of nibble boundaries simplifies the management of DNS reverse delegations. In an IPv6 prefix, each hexadecimal character represents one nibble, which is 4 bits. Therefore, the prefix length of a delegated prefix should always be a multiple of 4.
Some examples of nibble boundary masks; 48, 44, 40, 36, 32, 28, 24, etc.
Example of a non-nibble aligned prefix: 2001:0db8:0:4000::/50
2001:0db8:0000:4000:0000:0000:0000:0000 - 2001:0db8:0000:7fff:ffff:ffff:ffff:ffff |
2001:0db8:0000:8000:0000:0000:0000:0000 - 2001:0db8:0000:bfff:ffff:ffff:ffff:ffff |
Example of a nibble-aligned prefix; 2001:0db8::/48
2001:0db8:0000:0000:0000:0000:0000:0000 - 2001:0db8:0000:ffff:ffff:ffff:ffff:ffff |
2001:0db8:0001:0000:0000:0000:0000:0000 - 2001:0db8:0001:ffff:ffff:ffff:ffff:ffff |
AFRINIC has finalised the implementation of two new IPv6 related policies;
The policies introduce new sections and amend some, which are explained here.
Section 6.8.2 of the Consolidated Policy Manual requires member organizations to justify the number of end-sites and their need for the IPv6 PI address space, and once the IPv6 resources are assigned, the resource member must deploy the IPv6 provider-independent address space at each of their end-site(s) within 12 months from receiving the prefix.
The announcement of disaggregated IPv6 prefix is no longer forbidden by this new policy. However, the policy encourages members to aggregate any announcements of prefixes, to the extent practicable, so as to minimize global routing table growth.
Section 6.5.1.1(D) of the Consolidated Policy Manual makes it mandatory for LIR members to announce an IPv6 PA allocation within 12 months and; to the extent practicable, as a single aggregated prefix, so as to minimize global routing table growth. In some very special cases, the space may not be announced, however, it must be duly justified by the member to AFRINIC.
The IPv6 prefixes which are not in use or not being announced after 12 months are in violation of the respective policies mentioned above and shall be reclaimed and returned to the AFRINIC free pool. The holders of IPv6 prefixes with a valid reason not to announce their IPv6 prefix within 12 months are encouraged to contact AFRINIC (mail to: hostmaster@afrinic.net).
You may check if your IPv6 prefixes are compliant to the policy as follows;
Section 6.8.4 of the Consolidated Policy Manual allows End-User members to request for rectification of their initial IPv6 PI assignment if it no longer satisfies their needs. The request will be evaluated by AFRINIC and, if approved, the same address block will be “upgraded” to the new required prefix size. However, if the adjacent prefixes are already being used by other organizations or if such assignment would not leave sufficient space for subsequent assignments, the member will have to choose either to:
Note that a member can request the rectification of IPv6 PI space only once.
There are no new amendments made to the rectification of the initial PA allocation. As stipulated in section 6.5.1.3 of our Consolidated Policy Manual, LIR members may request for a rectification of their initial IPv6 PA allocation if it no longer satisfies their needs without the obligation to prove utilisation thresholds which applies for subsequent IPv6 PA allocations. The request will be evaluated by AFRINIC and, if approved, the same address block will be “upgraded” to the new required prefix size. However, if the adjacent prefixes are already being used by other organizations or if making the allocation would not leave sufficient space for subsequent allocations, the member will have to choose either to:
Note that a member can request the rectification of IPv6 PA space only once.
Any member requesting for the rectification of the initial assignment or allocation must provide a detailed IPv6 addressing plan demonstrating their needs for the next 12 months. In case the prefix will not be advertised, the member must inform AFRINIC and provide a reasonable justification.
To request for rectification of a PI Assignment, please follow the below steps;
To request for rectification of a PA Allocation, please follow the below steps;
You need to be an AFRINIC resource member with an IPv6 prefix and you must be compliant to the Contractual Obligation Checks.
While submitting the rectification request it is highly recommended to attach a detailed IPv6 addressing plan demonstrating your new needs.
To request for rectification of a PI Assignment, please follow the below steps;
To request for rectification of a PA Allocation, please follow the below steps;
We do not guarantee that your current IPv6 prefix is extendable to the new required prefix size.
Once you submit your request for the rectification of your initial IPv6 prefix, you shall be informed whether your prefix can be extended to the new required size or not.
If you are an LIR member and have opted to return your initial IPv6 prefix, it must be done within 6 months.
There is no timeframe specified in the policy for the return of PI assignment for End-User members, however, a reasonable amount of time will be granted to renumber and return the PI prefix.
You can request for rectification of your initial IPv6 allocation/assignment if it no longer satisfies your needs, the same address block will be “upgraded” to the new required prefix size.
However, if the adjacent prefixes are already being used by other organizations or if making the allocation would not leave sufficient space for subsequent allocations, then you can choose to receive a new block.
Take note that you can request the rectification of the IPv6 PA space only once.
