PinPoint-E EDGE/GPRS - User Guide, version 2.32 20
IP Manager and DNS
Note: If you will be using your PinPoint-E to communicate with another AirLink
modem and both are using IP Manager to translate dynamic IP addresses to
domain names, it is recommended that you set *DNSUSER to the IP address for
IP Manager. IP Manager’s updates occur more frequently than Your Wireless Ser-
vice Provider’s DNS servers decreasing the time between IP address change and
address resolution. Likewise, if your PinPoint-E routinely needs to contact
another modem or device with a Dynamic DNS domain and that modem or device
frequently changes its IP address, you may need to set *DNSUPDATE for fre-
quent updates.
