LABEL DESCRIPTION
Obtain an IP Address
Automatically When you enable this, the EMG3425-Q10A gets its IP address from the network’s
DHCP server (for example, your ISP). Users connected to the EMG3425-Q10A can
now access the network (i.e., the Internet if the IP address is given by the ISP).
The Web Configurator may no longer be accessible unless you know the IP address
assigned by the DHCP server to the EMG3425-Q10A. You need to reset the
EMG3425-Q10A to be able to access the Web Configurator again (see
Section 25.7
on page 181 for details on how to reset the EMG3425-Q10A).
Also when you select this, you cannot enter an IP address for your EMG3425-Q10A
in the field below.
Static IP Address Click this if you want to specify the IP address of your EMG3425-Q10A. Or if your
ISP or network administrator gave you a static IP address to access the network or
the Internet.
IP Address Type the IP address in dotted decimal notation. The default setting is 192.168.1.2.
If you change the IP address you will have to log in again with the new IP address.
Subnet Mask The subnet mask specifies the network number portion of an IP address. Your
EMG3425-Q10A will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing subnetting, use the subnet
mask computed by the EMG3425-Q10A.
Gateway IP Address Enter a Gateway IP Address (if your ISP or network administrator gave you one)
in this field.
DNS Server
First DNS Server
Second DNS Server
Third DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS server information
(and the EMG3425-Q10A's WAN IP address). The field to the right displays the
(read-only) DNS server IP address that the ISP assigns.
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 changes 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 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.
