NetBIOS is associated with which port range?

Explanation:
NetBIOS over TCP/IP uses a small set of ports that cover its three main services: name resolution, datagram messages, and sessions. Specifically, NetBIOS name service runs on UDP port 137, NetBIOS datagram service on UDP port 138, and NetBIOS session service on TCP port 139. So looking for a range that includes all three validates 137 through 139 as the NetBIOS-associated ports. The other ranges don’t align with these NetBIOS services, so they aren’t correct associations.
