1. A method for a list digest request operation, the method comprises: generating a payload section of a dispersed storage network (DSN) frame regarding the list digest request operation by: generating a start slice name field of the payload section to include a start slice name of a slice name range; generating an end slice name field of the payload section to include an end slice name of the slice name range; and generating a maximum response count field of the payload section to include a maximum slice name response count; and generating a protocol header of the DSN frame by: generating a payload length field of the protocol header to include a payload length that represents a length of the payload section; generating an operation code field to indicate the list digest request operation, wherein the list digest request operation requests a representation of slice names in the slice name range; and generating remaining fields of the protocol header.
