Sierra Wireless PINPOINT X HSUPA - Manual (Page 11)

Introduction to the PinPoint X
Rev 4.0 Oct.09 5
The PinPoint X will perform routing for all internet traffic to
and from the computers or other end devicse.
With the Raven XE in Ethernet Public mode, only one device
connected to the Ethernet port will receive the public IP
address which is the one provided by the cellular network. In
Ethernet Private mode, with a hub or switch connected to the
Ethernet port, the Raven XE will provide NAT for a range of
computers or other devices connected to the switch or hub and
Internet access to all of them.
Dynamic vs. Static IP Addresses
There are two types of addresses on networks: dynamic and
static.
• Dynamic addresses are assigned on a “need to have” basis.
Your PinPoint X might not always receive the same
address each time it connects with your cellular provider.
• Static addresses are permanently assigned to a particular
account and will always be used whenever your PinPoint
X connects to the Internet. The IP address will not be given
to anyone else.
Most ISPs (cellular included) use dynamic IP addresses rather
than static IP addresses since it allows them to reuse a smaller
number of IP addresses for a large number of customers. A
dynamic IP address is suitable for many common Internet
uses, such as web browsing, looking up data on another
computer system, or other client functions (such as data only
being sent out or only being received after an initial request).
Tip: If your account with your cellular provider includes a dynamic IP
address and you need a static IP, please consult your your cellular
provider Representative for more information about changing your
account for static IP support.
