Registration Authority

IEEE offers Registration Authority programs or registries which maintain lists of unique identifiers under standards and issue unique identifiers to those wishing to register them. The IEEE Registration Authority assigns unambiguous names to objects in a way which makes the assignment available to interested parties.

Registration Authority Improvements: Introducing more user-friendly product names, new products, updated information and support tools. Learn More.

*The leftmost bit in this table is the least significant bit and represents the address type designation bit (set to the value '1' - Group) in the DSAP field. The meaning and use of reserved Group LLC addresses are for further study. LSAP values that are neither assigned nor identified for unreserved use are reserved.

The following number corresponds to the number in parenthesis shown in the document reference column. 1) Used in ISO/IEC 8802-2 as the global DSAP address
