+#### Limit the number of hops for an unscoped flood message
+**Usage:**
+- `get flood.max.unscoped`
+- `set flood.max.unscoped <value>`
+
+**Parameters:**
+- `value`: Maximum flood hop count (0-64) for a packet without a scope (no region set)
+
+**Default:** `0xFF` - indicates it hasn't been set, will track flood.max until it is.
+
+**Note:** An alternative to `region denyf *`, setting `flood.max.unscoped` to a lower value such as `3` would allow for local unscoped messages to propagate, while preventing noisy neighbors from flooding a local region.
