CHAPTER 6
IP Manager
IP Manager translates a dynamic IP address to a fully qualified domain name so
you can contact the Raven by name as if it had a static IP.
Since Cingular frequently does not offer static IP addresses, IP Manager is a free
service provided by AirLink for your Raven to translate a dynamic IP address into a
fully qualified domain name so it can be contacted directly on the Internet.
• Dynamic IP addresses are granted only when a modem or other device is con-
nected and can change each time the modem or device reconnects to the net-
work.
• Static IP addresses are granted the same address every time the modem or
device is connected.
A dynamic IP address is suitable for many Internet activities such as web browsing,
looking up data on another computer system, data only being sent out, or data only
being received after an initial request. However, if you need to contact the Raven
directly, a device connected to the modem, or a host system using the Raven, a
dynamic IP won’t give you a reliable address to contact (since it may have changed
since the last time it was assigned).
