A separate series of steps is used to resolve host names on a network that uses the Domain Name System (DNS). On IPX/SPX networks, NetBIOS over IPX (NBIPX) resolves NetBIOS names to Internetwork Packet Exchange (IPX) addresses.

What has replaced NetBIOS?

Today, DNS has replaced WINS, since Microsoft made changes to NetBIOS, allowing it to use the TCP/IP stack to perform its job (NetBIOS over TCP/IP) and most DNS servers are able to handle NetBIOS requests. ...
