2.2.6 Configuring DHCP Server to Assign WINS Server Addresses
For Microsoft Windows-based DHCP clients that communicate through NetBIOS
protocol, the host name-to-IP address translation is carried out by Windows internet
naming service (WINS) servers. So you need to perform WINS-related configuration for
most Windows-based hosts. Currently, you can configure up to eight WINS addresses
for a DHCP address pool.
Host name-to-IP address mappings are needed for DHCP clients communicating
through NetBIOS protocol. According to the way to establish the mapping, NetBIOS
nodes fall into the following four categories:
z B-node. Nodes of this type establish their mappings through broadcasting (The
character b stands for the word broadcast). The source node obtains the IP
address of the destination node by sending the broadcast packet containing the
host name of the destination node. After receiving the broadcast packet, the
destination node returns its IP address to the source node.
z P-node. Nodes of this type establish their mappings by sending unicast packets to
WINS servers. (The character p stands for peer-to-peer). The source node sends
the unicast packet to the WINS server. After receiving the unicast packet, the
WINS server returns the IP address corresponding to the destination node name
to the source node.
z M-node. Nodes of this type are p-nodes mixed with broadcasting features (The
character m stands for the word mixed), that is to say, this type of nodes obtain
mappings by sending broadcast packets first. If they fail to obtain mappings, they
send 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. (The
character h stands for the word hybrid), that is to say, this type of nodes obtain
mappings by sending unicast packets to WINS servers first. If they fail to obtain
mappings, they send broadcast packets to obtain mappings.
