I've been looking at the current Soft Landing proposal - the one that is
in existence and the one that I contributed a little bit to (thanks


Phase 1:
When we hit the last /8, Phase 1 reduces the max size of an
allocation/assignment from /10 to /13. It also carves off a /12 for
unforeseen use. This continues until we have a /11 left.
This will allow for 7 x /11's and a /12 - if people choose the largest
possible sizes. This will still take a while to go through.

Phase 2:
Allow people to get up to a /22. People can come back multiple times.
There are 2048 of these /22 blocks available. This would take a while to
burn through, simply because the process is a bit slow.

Then we are finished.


However - the Unforeseen /12 could still be used.
We already have reserves for IXP's and Critical infrastructure.

I'd like to see a revision that there is then a Phase 3:

That the /12 can be given out in /22's (there are 1024 of these) but
only to people with a total of less than a /21 (including what they ask
for). ie - New people could come back once. This I believe will last
multiple years.

I don't believe we need any further reserves.

We only need to last another two or three years.

Lastly - any addresses from Phase 2 or 3 can never be transferred, (M&A
included) and must be returned to AFRINIC for re-deployment.
