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 IPv4 DNS Configuration in the Layer 3 - IP Services Configuration Guide.
Follow these steps to configure a domain name suffix in the DHCP address pool:

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.
