So you need to perform WINS-related configurationfor most Windows-based hosts. Currently, you can configure up to eight WINSaddresses for a DHCP address pool.Host name-to-IP address mappings are needed for DHCP clients communicatingthrough NetBIOS protocol. According to the way to establish the mapping, NetBIOSnodes fall into the following four categories:z B-node. Nodes of this type establish their mappings through broadcasting (Thecharacter b stands for the word broadcast). The source node obtains the IPaddress of the destination node by sending the broadcast packet containing thehost name of the destination node. After receiving the broadcast packet, thedestination node returns its IP address to the source node.z P-node. Nodes of this type establish their mappings by sending unicast packetsto WINS servers. (The character p stands for peer-to-peer). The source nodesends the unicast packet to the WINS server. After receiving the unicast packet,the WINS server returns the IP address corresponding to the destination nodename to the source node.z M-node. Nodes of this type are p-nodes mixed with broadcasting features (Thecharacter m stands for the word mixed), that is to say, this type of nodes obtainmappings by sending broadcast packets first. If they fail to obtain mappings, theysend unicast packets to the WINS server to obtain mappings.z H-node. Nodes of this type are b-nodes mixed with peer-to-peer features. (Thecharacter h stands for the word hybrid), that is to say, this type of nodes obtain
