11.4 DHCP Client List Screen
The DHCP table shows current DHCP client information (including IP Address, Host Name and MAC
Address) of network clients using the EMG2926-Q10A’s DHCP servers.
Configure this screen to always assign an IP address to a MAC address (and host name). Click
Network > DHCP Server > Client List
.
Note: You can also view a read-only client list by clicking
Monitor > DHCP Server
.
MAC Address

Type the LAN IP address of a computer on your LAN.
DNS Server
DNS Servers
Assigned by DHCP
Server
The EMG2926-Q10A sends a DNS (Domain Name System) server IP address (in the
order you specify here) to the DHCP clients. The EMG2926-Q10A only sends this
information to the LAN DHCP clients when you enable
DHCP Server
. When you disable
DHCP Server
, DHCP service is disabled and you must have another DHCP server on
your LAN, or else the computers must have their DNS server addresses manually
configured.
First DNS Server
Second DNS Server
Third DNS Server
Select
Obtained From ISP
if your ISP assigns DNS server information (and the
EMG2926-Q10A's WAN IP address) dynamically. The field to the right displays the (read-
only) DNS server IP address assigned by the ISP.
Select
User-Defined
if you have the IP address of a DNS server. Enter the DNS server's
IP address in the field to the right. If you chose
User-Defined
, but leave the IP address
set to 0.0.0.0,
User-Defined
will change to
None
after you click
Apply
. If you set a
second choice to
User-Defined
, and enter the same IP address, the second
User-
Defined
changes to
None
after you click
Apply
.
Select
DNS Relay
to have the EMG2926-Q10A act as a DNS proxy. The EMG2926-
Q10A's LAN IP address displays in the field to the right (read-only). The EMG2926-Q10A
tells the DHCP clients on the LAN that the EMG2926-Q10A itself is the DNS server. When
a computer on the LAN sends a DNS query to the EMG2926-Q10A, the EMG2926-Q10A
forwards the query to the EMG2926-Q10A's system DNS server (configured in the
WAN
> Internet Connection
screen) and relays the response back to the computer. You can
only select
DNS Relay
for one of the three servers; if you select
DNS Relay
for a
second or third DNS server, your selection will change to
None
after you click
Apply
.
Select
None
if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
Apply
Click
Apply
to save your changes to the EMG2926-Q10A.
