Net BIOS Scope ID - Network Encyclopedia
Definition of Net BIOS Scope ID.
NetBIOS Scope ID is a character string appended to a NetBIOS name of a host that identifies the host as belonging to a specific group.
You can use NetBIOS scope IDs to segment the flat NetBIOS namespace into a series of subspaces. Two hosts can communicate only if they have the same NetBIOS scope ID and belong to the same subspace.
The total length of a NetBIOS name plus scope ID cannot exceed 256 characters.
