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.
