The following example protects all IP addresses within the address range of
192.168.19.51 to 192.168.19.55 using the dhcp-authority command.
The next time that the attached cable modems reinitialize, those cable
modems assigned IP addresses that fall within the DHCP Authority range are
tagged by the DHCP server as type Other. Those entries shown as type Other
are protected by the DHCP Authority feature. Entries shown as "dynamic"
are fixed IP addresses.
