Shouldn't 23.128.0.0/10<http://23.128.0.0/10> be put back into the pool?

Bryan -

  23.128.0.0/10 isn’t on loan to RIPE; it is the permanently reserved block for IPv6
  transition (see ARIN NRPM 4.10 "Dedicated IPv4 block to facilitate IPv6 Deployment”),
  of which RIPE is doing testing with 4 /24’s (and has asked to continue the testing
  of those blocks, so long as we don’t need them back sooner.)

Thanks,
