By default, global address pools and VLAN interface address pools are not configured
with any DHCP client domain name.
If you execute the dhcp server domain-name command multiple times, the newly
configured DHCP client domain name overwrites the existing one.

13.3.6 Configuring DNS Server Address for DHCP Clients

When a host uses a domain name to access the Internet, the domain name must be
translated into an IP address. Domain name system (DNS) is responsible for the
translation. Therefore, when a DHCP server assigns an IP address to a DHCP client, it
must also send a DNS server address to the client. At present, you can configure up to
eight DNS server addresses for one DHCP address pool.
