2.2.4 Peer Names

Protocols and higher-layer applications use Peer Names for publishing endpoint information and to resolve them to endpoint information. A Peer Name MUST be a Unicode string conforming to the following syntax (specified here using Augmented Backus-Naur Form (ABNF) [RFC5234]).

 peername = authority "." classifier
 authority = "0" / secureauthority
 secureauthority = 40auchar
 auchar = DIGIT / %d97-102
 classifier = 0*149clchar
 clchar = %x0001-FFFF ; any non-NULL Unicode character
