Interface Address Pool-based DHCP Server Configuration 135
The dhcp server forbidden-ip command can be executed repeatedly. That is, you can
repeatedly configure IP addresses that are not dynamically assigned to DHCP clients.
Configuring DNS
Services for DHCP
Clients
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.
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 as well
while the former assigns IP addresses to the DHCP clients.

Optional
By default, all IP addresses in a
DHCP address pool are
available for being dynamically
assigned.
