DHCP Client
(Available in Router or SOHO Router mode only.) Displays
the device’s WAN IP address, netmask, DNS servers, and
gateway while the device is operating as a DHCP client of
an external DHCP server.
Interface
Displays the interface that connects to the
WAN.
IP Address
Displays the IP address assigned by an
external DHCP server connected to the WAN interface.
If an external DHCP server is not found, the IP address
will use the DHCP Fallback IP defined in the WAN Network
Settings. See “WAN Network Settings” on page 32 for
additional details.
Netmask
Displays the Netmask assigned by an external
DHCP server connected to the WAN interface. If an
external DHCP server is not found, the IP address will use
the DHCP Fallback Netmask defined in the WAN Network
Settings. See “WAN Network Settings” on page 32 for
additional details.
Gateway
Displays the gateway address assigned by an
external DHCP server connected to the WAN interface.
Primary/Secondary DNS IP
The Domain Name System
(DNS) is an Internet “phone book” that translates domain
names to IP addresses. These fields identify the server IP
addresses that the device uses for translation.
DHCP Server
Displays the IP address of the external
DHCP server that assigns the WAN IP address to the
device.
Domain
Displays the domain name.
Total Lease Time
Shows the total time (validity) of the
leased IP address assigned by the external DHCP server.
Remaining Lease Time
Displays the remaining time
of the leased IP address assigned by the external DHCP
server.
Renew
To request new IP settings from the external
DHCP server, click Renew.
Release
To release the current IP settings, click Release.
Refresh

ARP Table
Lists all the entries of the Address Resolution Protocol
(ARP) table currently recorded on the device.
ARP is used to associate each IP address to the unique
hardware MAC address of each device on the network. It
is important to have unique IP addresses for each MAC
address or else there will be ambiguous routes on the
network.
IP Address
Displays the IP address assigned to a network
device.
MAC Address
Displays the MAC address of the device.
Interface
Displays the interface that connects to the
device.

Bridge Table
(Available in Bridge mode only.) The table displays the
entries in the system Bridge Table.
Bridge
The name of the bridge.
MAC Address
The network device identified by its MAC
address.
Interface
The Bridge Table shows which bridge port
or interface, LAN (Ethernet) or WLAN (Wireless), the
specific network device is associated with. airOS can
forward packets only to the specified port of the device,
eliminating redundant copies and transmits.
Aging Timer
Displays aging time for each address entry
(in seconds). After a specific timeout, if the device has not
seen a packet coming from a listed address, it will delete
that address from the Bridge Table.
