NTP Extension Field Types

Registration Procedure(s)

Specification Required

Expert(s)

Dr.-Ing. Kurt Kristof Teichel, Miroslav Lichvar, David Venhoek

Reference

[RFC5905][RFC5906][RFC9748]

Note

Field Types in the range 0xF000 through 0xFFFF, inclusive, are reserved
for experimentation and development. IANA cannot assign them. Both NTS
Cookie and Autokey Message Request have the same Field Type; in practice
this is not a problem as the field semantics will be determined by other
parts of the message.
    

Note

The "Reserved for historic reasons" is for differences between the
original documentation and implementation of Autokey and marks the
erroneous values as reserved, in case there is an implementation that
used the registered values instead of what the original implementation
used.
