[rpd] Legacy addresses in Afrinic region

There is *WAY* more than that.

You have a significant amount of space sitting in academia that came from ARIN and even pre-arin days.

I am going to decline to comment on the exact ranges and asn’s since I believe it would not be polite to do so and will let the space owners speak for themselves – but I will say that in a previous job I was controlling the announcements for very close to a /12 worth of legacy space distributed amongst multiple blocks – and that wasn’t anywhere near all of it on the continent.

A lot of this space came either from ARIN (or quite probably pre-dates even ARIN)

Subject: [rpd] Legacy addresses in Afrinic region


It has seemed to me that there has been a lack of information in some of the policy debates. I finally got around to looking up how much legacy address space is in the Afrinic region.

When Afrinic was founded, legacy address space was transferred to it from RIPE-NCC. I think address space from ARIN had already been transferred to RIPE-NCC before that, so the RIPE-Afrinic transfer was all of it, but I'm not completely certain, and if anyone else remembers better, please correct me.

The list of legacy IPv4 addresses transferred is at<> and also<>

A total of 271,604 legacy IPv4 addresses was transferred.

Within this series were three Class B blocks (/16s) currently registered to the European Space Agency, Sweden, and IDSC in Egypt. There was also one /17 currently registered to TE Data in Egypt.

Distribution of the blocks:

  *   Three Class Bs (/16s)
  *   One /17
  *   One /19
  *   One /21
  *   One block of six /24s
  *   Seven blocks of five /24s
  *   Four /22s
  *   Eleven /23s
  *   Forty-six /24s
  *   One /26 (!?)

Unless there were separate legacy block transfers from ARIN or APNIC, or other addresses have been re-registered into Afrinic since its founding, this is the total of legacy address space in the region.

I hope this is useful information to the community.
