Service Codes Created 2005-08-31 Last Updated 2011-02-10 This registry is also available in plain text. Registry included below * Service Codes Service Codes Registration Procedures Specification Required or First Come First Served Reference [RFC4340] Note Service Codes are big-endian 32-bit numbers. Some Service Codes also have an ASCII string representation; when a Service Code may be represented in "SC:" format according to the rules in [RFC4340], Section 8.1.2, the ASCII column shall provide that interpretation. Here is an example allocation: 1717858426 fdpz Frobodyne Plotz Protocol [RFCWXYZ] Service Codes whose high-order 8 bits equal the value 63 (ASCII '?') are reserved for Private Use; this is the range 1056964608-1073741823. Service Codes whose component bytes' values are each in the set {32, 45-57, 65-90} are allocated using the Specification Required policy (this corresponds to no simple range). All other Service Codes are allocated using the First Come First Serve (FCFS) policy. See the following C Program to analyze one or more Service Codes, given numerically or as strings, and print their allocation classes. http://www.iana.org/assignments/c-program-service-codes C Program provided by Eddie Kohler, on 8/30/05.
