DHCP allocation pool will start at 192.168.100.100.
For subnets greater than /24, it may be greater than 255 to span
subnets. Alternatively, specify in IP address notation using the
wildcard ‘0’ where the octet is required to inherit bits from the
interface IP addess.
Example: to define a DHCP scope starting from 10.1.20.0 on an
interface with 10.1.0.0/16 address, set start to 0.0.20.1
