Configuring a Domain Name Suffix for the Client
You can specify a domain name suffix in each DHCP address pool on the DHCP server to provide the
clients with the domain name suffix. With this suffix assigned, the client only needs to input part of a
domain name, and the system will add the domain name suffix for name resolution. For details about
DNS, refer to DNS Configuration in the IP Services Volume.
Follow these steps to configure a domain name suffix in the DHCP address pool:
To do… Use the command… Remarks
Enter system view system-view —
Enter DHCP address pool view
dhcp server ip-pool pool-name
[ extended ]
—
Specify a domain name suffix domain-name domain-name
Required
Not specified by default.
Configuring DNS Servers for the Client
When a DHCP client wants to access a host on the Internet via the host name, it contacts a Domain
Name System (DNS) server holding host name-to-IP address mappings to get the host IP address. You
can specify up to eight DNS servers in the DHCP address pool.
Follow these steps to configure DNS servers in the DHCP address pool:
To do… Use the command… Remarks
Enter system view system-view —
Enter DHCP address pool view
dhcp server ip-pool
pool-name [ extended ]
—
Specify DNS servers dns-list ip-address &<1-8>
Required
Not specified by default.
Configuring WINS Servers and NetBIOS Node Type for the Client
A Microsoft DHCP client using NetBIOS protocol contacts a Windows Internet Naming Service (WINS)
server for name resolution. Therefore, the DHCP server should assign a WINS server address when
assigning an IP address to the client.
You can specify up to eight WINS servers in a DHCP address pool.
You need to specify in a DHCP address pool a NetBIOS node type for the client to approach name
resolution. There are four NetBIOS node types:
z
b (broadcast)-node: The b-node client sends the destination name in a broadcast message. The
destination returns its IP address to the client after receiving the message.
z
p (peer-to-peer)-node: The p-node client sends the destination name in a unicast message to the
WINS server, and the WINS server returns the destination IP address.
z
m (mixed)-node: A combination of broadcast first and peer-to-peer second. The m-node client
broadcasts the destination name, if no response is received, then unicasts the destination name to
the WINS server to get the destination IP address.
