# One-byte message type allocations This table lists additional message type IDs that various BIPs have assigned or proposed for assignment.

If multiple BIPs make conflicting assignments for message type IDs, that may lead to multiple entries for the same message type ID in this table. BIPs that are in Draft status may be included in the table, and as a result, the IDs and messages they define may be changed in future.
