Introduction to Raven X EV-DO
Dynamic vs. Static IP Addresses
As stated above, when your Raven X registers on Verizon’s network, it receives an IP address. There are two types of addresses on networks: dynamic and static.
•Dynamic addresses are assigned on a “need to have” basis. Your Raven 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 Raven 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).
If you need to contact your Raven X, a device connected to the modem, or a host system using the modem 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, page 11) to translate your IP address into to a domain name.
Caution: If you want to connect remotely to your Raven X using TCP/IP, the IP address given to your modem by the network cannot be a private or internal IP address (such as a special private network) unless you are on the same network or inside that network’s firewall (such as with frame relay).
Using Your Raven X to Connect to the Internet
In Public Mode, your Raven X will pass the IP address from Verizon’s network to your device or computer. In Private Mode, your modem will assign configured, static local network IP addresses for the modem and your device.
The modem will perform a
If you need to have more than one device connected to the Internet through the modem, you will need to have a router connected to the modem. The modem would provide the
You can connect directly through your Raven X to the Internet using the Ethernet port or use PPPoE for a password protected connection. For a direct connection, the Raven X features DHCP (enabled by default) so you don’t need to worry about setting up an IP address on your computer. DHCP works with both Private and Public Modes.
