Local LAN IP address information to obtain

Your ISP will need to provide you with the following information:

The default gateway IP address

Remote IP address

Local IP address or addresses and subnet mask

Note: In a single IP address service, your ISP will refer to your computer’s IP address. However, when your connection is configured with a router, this becomes the router’s WAN IP address.

Primary and secondary domain name server (DNS) IP addresses

Domain name (usually the same as the ISP’s domain name unless you have registered for your own individual domain name)

Note: The default gateway, WAN address and mask, DNS, and domain name are all obtainable via WAN DHCP, if your ISP supports it.

With Network Address Translation

If you are using NAT, you should obtain the following:

If you are connecting to a remote site using Network Address Translation on your router, your provider will not define the IP address information on your local LAN. You can define this information based on an IP configuration that may already be in place for the existing network. Alternatively, you can use the default IP address range used by the router, where 192.168.1.1 is the default IP address of the router.

Without Network Address Translation

If you are not using Network Address Translation, you will need to obtain all of the local LAN IP address information from your ISP and you will need to pay for an IP address for each device on the network.

If you are not using NAT, you should obtain:

The Ethernet IP address for your Netopia R910

The Ethernet IP subnet mask for your Netopia R910

An IP address for each device on your network, in the same network range as the Netopia R910.
