This read-only IP address reports the default IP address of the unit at a given rack position, and because the table can be read from any one position, it lets an administrator see and even alter the addresses of other positions from a single management point. This is useful for managing an entire rack's IP addressing without needing to log into each board individually. For example, an admin connected to just one position could review this field across the whole table to audit or fix IP address assignments for every board in the rack.
