Note: If you will be using your modem 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 cellular provider’s DNS servers

decreasing the time between IP address change and address

resolution. Likewise, if your modem 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 frequent updates.
