Viewing the dynamic IP list

If you have configured your DFL-500 NPG as a DHCP server, you can view a list of IP addresses that the DHCP server has added, their corresponding MAC addresses and the expiry time and date for these addresses. The DFL-500 NPG adds these addresses to the dynamic IP/MAC list and if IP/MAC binding is enabled, the addresses in the dynamic IP/MAC list are added to the list of trusted IP/MAC address pairs. For more information about IP/MAC binding, see IP/MAC binding.

To view the dynamic IP list:

•Go to System > Network > DHCP .

•Select Dynamic IP List.

The dynamic IP list appears.
