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 more information
about DNS, see the chapter “IPv4 DNS configuration.”
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
A DHCP client contacts a Domain Name System (DNS) server to resolve names. 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

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.
