2.3.5 Configuring DNS Services for the DHCP Server

If a host accesses the Internet through domain names, DNS is needed to translate the
domain names into the corresponding IP addresses. To enable DHCP clients to
access the Internet through domain names, a DHCP server is required to provide
DNS server addresses while assigning IP addresses to DHCP clients. Currently, you
can configure up to eight DNS server addresses for a DHCP address pool.
On the DHCP server, you can configure domain names to be used by DHCP clients
for address pools. After you do this, the DHCP server provides the domain names to
the DHCP clients while the DHCP server assigns IP addresses to the DHCP clients.
Follow these steps to configure DNS services for the DHCP server:
