Note:
In the same DHCP global address pool, the network command can be executed
repeatedly. In this case, the new configuration overwrites the previous one.
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.
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.
2.2.5 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.
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.
