jcifs.netbios.NbtAddress

This class represents a NetBIOS over TCP/IP address. Under normal conditions, users of jCIFS need not be concerned with this class as name resolution and session services are handled internally by the smb package.

Applications can use the methods getLocalHost, getByName, and getAllByAddress to create a new NbtAddress instance. This class is symmetric with {@link java.net.InetAddress}.

About NetBIOS: The NetBIOS name service is a dynamic distributed service that allows hosts to resolve names by broadcasting a query, directing queries to a server such as Samba or WINS. NetBIOS is currently the primary networking layer for providing name service, datagram service, and session service to the Microsoft Windows platform. A NetBIOS name can be 15 characters long and hosts usually registers several names on the network. From a Windows command prompt you can see what names a host registers with the nbtstat command.

 C:\>nbtstat -a 192.168.1.15 NetBIOS Remote Machine Name Table Name               Type         Status --------------------------------------------- JMORRIS2        <00>  UNIQUE      Registered BILLING-NY      <00>  GROUP       Registered JMORRIS2        <03>  UNIQUE      Registered JMORRIS2        <20>  UNIQUE      Registered BILLING-NY      <1E>  GROUP       Registered JMORRIS         <03>  UNIQUE      Registered MAC Address = 00-B0-34-21-FA-3B

The hostname of this machine is JMORRIS2. It is a member of the group(a.k.a workgroup and domain) BILLING-NY. To obtain an {@link java.net.InetAddress} for a host one might do:

 InetAddress addr = NbtAddress.getByName( "jmorris2" ).getInetAddress();

From a UNIX platform with Samba installed you can perform similar diagnostics using the nmblookup utility. @author Michael B. Allen @see java.net.InetAddress @since jcifs-0.1
