1.  Introduction

   The Domain Name System (DNS) is primarily used to map human-memorable
   names to IP addresses, which are used for routing but generally not
   meaningful for humans.

   Peer-to-Peer (P2P) systems use specific decentralized mechanisms to
   allocate, register, manage, and resolve names.  However, the
   hierarchical nature of DNS makes it unsuitable for various P2P Name
   Systems.  Such P2P Name Systems operate entirely outside of DNS,
   independently from the DNS root and delegation tree.

   As compatibility with applications using domain names is desired,
   these P2P overlay networks often define exclusive alternative Top-
   Level Domains to avoid conflict between the P2P namespace and the DNS
   hierarchy.

   In order to avoid interoperability issues with DNS as well as to
   address security and privacy concerns, this document registers a set
