dhcp server forbidden-ip

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