mask netmask: Network mask of the IP address pool. Natural mask will be
adopted if the parameter is not specified.
Description
Using the network command, you can configure an IP address range used for
dynamic allocation. Using the undo network command, you can delete the
configuration.
By default, no IP address range has been configured for dynamic allocation.
Each DHCP address pool can be configured with a network segment and the new
configuration will replace the old one. If the system requires several such address
segments, you should configure them in multiple address pools.
For the related commands, see dhcp server ip-pool and dhcp server forbidden-ip.
Example
Use 192.168.8.0/24 as the address space for DHCP address pool 0.

Description
Using the option command, you can configure the self-defined options for a
DHCP global address pool. Using the undo option command, you can delete the
DHCP self-defined options.
New options are emerging along with the development of DHCP. In order to
accommodate these options, manual option addition is supported so that they can
be added into the attribute list maintained by the DHCP server.
For the related commands, see dhcp server option (in interface view) and dhcp
server option interface (in system view).
