Note:
The dhcp server forbidden-ip command can be executed repeatedly. That is, you
can configure multiple IP addresses that are not dynamically assigned to DHCP
clients.
Use the dhcp server forbidden-ip command to configure the IP addresses that are
not assigned dynamically in global address pools and interface address pools.
If an IP address that is not to be automatically assigned has been configured as a
statically-bound IP address, the DHCP server still assigns this IP address to the
client whose MAC address has been bound.

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 interface address pool.
