When LLMNR/NBT-NS is used to resolve a name, any host on the network can reply. So, Responder is one of such tools that poisons the request.

What is NetBIOS networking?

NetBIOS (/ˈnɛtbaɪɒs/) is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol.

What is Nbns protocol?

NBNS (sometimes called WINS) stands for NetBIO Name Service, which is a protocol for name resolution. NBNS performs the same function as LLMNR, but using UDP broadcast packets instead of multi cast packets. Browsers normally only attempt to use NBNS after attempts to use LLMNR have failed.

Do I need NetBIOS?

NetBIOS is legacy and you only need it if you are using old applications or old versions of Windows that require it or use WINS. If your running applications or OS's that require it still, NetBIOS is probably not the real problem here.
