Which port is associated with NetBIOS name service?

Explanation:
NetBIOS name service is the component that maps NetBIOS names to IP addresses in networks using NetBIOS over TCP/IP. It uses port 137, and this port is used for both UDP and TCP, which is why the correct identification is 137/TCP, UDP for NetBIOS name service. The other ports correspond to different services: 138 is NetBIOS datagram service, 139 is NetBIOS session service, 500/UDP is ISAKMP (IPsec), and 179/TCP is BGP.
