This document is an appeal to the Internet community to return unused
address space, i.e. any block of consecutive IP prefixes, to the

registries, for reapportionment.  Similarly, an appeal is issued to

address blocks to the IANA for reapportionment.  This RFC is the
product of the CIDR Deployment Working Group of the IETF.
