[AfriNIC-rpd] IPv4 Soft Landing Policy

[Douglas Onyango]

Graham,
Thanks for the well reasoned argument....
I have to take a little while to do the maths (terrible time at work), but meantime if anyone else has a comment on this......it's most welcome.

Life is the educators practical joke in which you spend the first half learning, and the second half learning that everything you learned in the first was wrong.

I think that the minimum allocation size of /24 is reasonable. During the dying days of IPv4 many ASNs are likely to announce their IPv6 space and just one /24 for legacy purposes.

The rest of the paragraph concerns me:

You state that an LIR may request no more than a /23 and up to 4 of those. Four /23s is /21 of address space. In the case that an LIR determines that they require /21 of address space they submit 4 applications for address space (concurrently or sequentially). This results in x4 the volume of admin by the LIR and x4 the volume of work for the AfriNIC resource officer with no perceived benefit to the community.

You limit each LIR to a /21 of addressing resources. That provides for 7680 (excluding the reserved /12) LIRs to obtain maximum allocations. AfriNIC currently has 1009 members and a growth rate of less than 100 members per year[1]. This means that at the end of 5 years 80% of our final /8 will be locked up and un-allocatable under this policy.

I think that it would be a good idea to have an upper bound on allocations to LIRs during the exhaustion phase. I would like to propose that /18 per LIR would be a far more reasonable limit in terms of our current membership trends.

I personally don't see any benefit in restricting the size of each individual application to a level lower than this upper bound. If an LIR can justify the need for a certain size of prefix under our policies then there is no benefit to be had by forcing additional administrative overhead.
