  1. Revised ipv4 assignment policy for ixps A Policy proposal draft Remco van Mook, Asteroid Will van Gulik, Romandix Will Hargrave, LONAP

  2. Current policy • There is a reserved /16 pool of IPv4 for IXPs • IXPs can get a single block, ranging from a /24 to a /22 • Any unused assignments from IXPs will be returned to this pool

  3. CHANGES • Textual cleanup • Increase the reserved pool to a from a /16 to a /15 • Reduce the maximum assignment to a /23 • Reduce the minimum assignment to a /27 • The default assignment stays a /24

  4. rationale • The original policy dates from 2012 – since then, about half of the pool has been used • Globally routable is less of a concern for IXP assignments • We’ll need globally unique IPv4 for IXP purposes for a long time • Existing assignments are safe

  5. Arguments against • It no longer provides for large IXPs (> /23) • It moves depletion of the free pool forward by about a week
