This page displays the WAN IP parameters assigned dynamically by your ISP, including IP
address, Subnet Mask, Default Gateway, etc.
IP Address - The IP address assigned by your ISP dynamically.

Subnet Mask - The subnet mask assigned by your ISP dynamically.

Default Gateway - The default gateway assigned dynamically by your ISP.

MTU Size (in bytes) - The normal MTU (Maximum Transmission Unit) value for most

Ethernet networks is 1500 Bytes. For some ISPs you need to modify the MTU. But this is
rarely required, and should not be done unless you are sure it is necessary for your ISP
connection.
If your ISP gives you one or two DNS IP addresses, select Use These DNS Servers and enter
the Primary DNS and Secondary DNS into the correct fields. Otherwise, the DNS servers will be
assigned from ISP dynamically.
Primary DNS - Enter the DNS IP address in dotted-decimal notation provided by your ISP.

Secondary DNS - Enter another DNS IP address in dotted-decimal notation provided by your

ISP.
Click the Renew button to renew the IP parameters from your ISP.
Click the Release button to release the IP parameters.

Note:
If you get Address not found error when you access a Web site, it is likely that your DNS servers
are set up improperly. You should contact your ISP to get DNS server addresses.
Get IP with Unicast DHCP - A few ISPs' DHCP servers do not support the broadcast

applications. If you can't get the IP Address normally, you can choose Unicast. You generally
need not to check this option.
