Figure 6: AceManager: DNS
*DNS1 and *DNS2 ‐ The primary and secondary DNS servers set by your cellular provider when your modem gets its IP address.
*DNSUSER ‐ Set this, if desired, to an additional DNS server to query first before the primary or secondary (just as a hosts file is queried first on a computer). If *DNSUSER is set to 0.0.0.0, it will be ignored.
*DNSUPDATE ‐ This command sets how often you want DNS Updates to be requested. Otherwise the modem will only send updates when it is reset, powered up, or the IP address is granted by network changes.
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.
PPP-Peer
The Raven and PinPoint use the unqualified domain name of “ppp‐peer” when it is in PPP or SLIP address mode to resolve the address of the device or computer connected via PPP or SLIP address. If the modem is not in PPP or SLIP address mode, “ppp‐peer” will resolve to 0.0.0.0.
