3. When your PinPoint X has received its IP address from Verizon, a connection
to the Internet or the cellular network is also available for computers or other
devices connected directly to the PinPoint X.
The PinPoint X will perform routing for all internet traffic to and from the
computers or other end devicse.
With the PinPoint X 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 PinPoint X 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
Verizon.
•
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 Verizon includes a dynamic IP address and you need a static IP,
please consult your Verizon Representative for more information about changing your
account for static IP support.
If you need to contact your PinPoint X, a device connected to the PinPoint X, or a
host system using the PinPoint X from the Internet, you need to have a known IP
(such as one which is static) or domain name (an IP address which is converted
by a DNS server into a word based name). If you have a dynamic IP address for
your modem, you can use a Dynamic DNS service (such as IP Manager) to
translate your IP address into to a domain name.
