Figure 64: Example of Addressing parameters showing available private IP addresses
In this example, the satellite modem is assigned a private IP address (LAN Port Address) of
192.168.0.1.
There are 253 available private IP addresses that can be assigned to computers connecting to
the satellite modem. These addresses are in the range from 192.168.0.2 to 192.168.0.254 (the
Last Usable IP Address).
Public IP address
Figure 65: Example of Addressing parameters showing one available public IP address on page
108 is an example of System Information page address parameters for a satellite modem with a
service plan that provides one public IP address. Some service plans provide multiple public IP
addresses.
Figure 65: Example of Addressing parameters showing one available public IP address
In this example, the satellite modem is assigned the public IP address (LAN Port Address)
97.73.73.65. The modem’s DHCP server has only one public IP address to assign to a connecting
computer: 97.73.73.66 (the Last Usable IP Address).
For instructions on configuring a public IP address on your computer, see the applicable section
in
Configuring a computer for a public IP address on page 117. Find the section that applies to
your computer operating system.
Multiple public IP addresses
If a service plan provides more than one public IP address, the range (or difference) from the
LAN Port Address to the Last Usable IP Address will be greater than one. For example, if the
LAN Port Address is 97.73.73.65 and the Last Usable IP Address is 97.73.73.70, the range (or
difference) is 5, meaning there are five available public IP addresses.
If you don't know the modem’s public IP address…
To access the satellite modem when the service plan provides a public IP address, you need to
know the public IP address of the satellite modem (the LAN Port Address). If you do not know
the LAN Port Address (and you cannot access the System Information page), you can set a
link
local address on your computer as explained below:
1. Use the Windows Control Panel on the connected computer to open the Local Area Connection
Properties dialog and then the Internet Protocol (TCP/IP) Properties dialog. If you need more
specific instructions, see
Configuring a computer for a public IP address on page 117.
2.
In the Internet Protocol Properties dialog, click Use the following IP address.
