Title:
  single allowed address pair rule can exhaust entire ipset space

  Fix Released
Status in neutron juno series:

Bug description:
  The hash type used by the ipsets is 'ip' which explodes a CIDR into
  every member address (i.e. 10.100.0.0/16 becomes 65k entries). The
  allowed address pairs extension allows CIDRs so a single allowed
  address pair set can exhaust the entire IPset and break the security
  group rules for a tenant.
