A block is one contiguous IEEE assignment: an MA-L covers 224 addresses, an MA-M 220, an MA-S 212. Country is parsed from the registrant address in the IEEE feed and is blank when it can't be determined. Private blocks (registrants who asked IEEE to withhold their name) and blocks IEEE no longer lists are shown as their own figures here, and are excluded from every other figure and from the vendor directory.
