8.4.2 Eairlink.com
As a service, ProSoft Technology offers an IP Manager server, which can be
used for any RadioLinx Intelligent Cellular modem.
Note: The IP Manager service is currently not a guaranteed service, although every effort is made
to keep it operational 24/7.

Important: Because many modems use the IP Manager service, you must have a unique name for
your modem.
8.5 Understanding DNS
The RLXIC-SG has the ability to query DNS servers in order to translate domain
names into IP addresses. This allows you to use domain names in place of IP
addresses for most of the configuration options requiring IP addresses. This is
important if your RLXIC-SG will need to contact another modem or other device
that has a domain name but an unknown or dynamic IP address (such as
another remote RLXIC-SG using IP Manager).
8.5.1 Configuring DNS
Generally, when your RLXIC-SG receives its IP address from Provider as part of
the connection process, it will also receive the DNS servers to use for resolving
(or translating) names to IP addresses which it will automatically configure in the
modem settings. Unless your RLXIC-SG will be used on a network with other
modems or devices which have names internal to the local network or frequently
changing IP addresses, the DNS servers provided by Provider should be all you
need.
If the RLXIC-SG will be communicating with a device that has a domain name
but changes its IP address frequently (such as another RadioLinx modem using
IP Manager) or is on a network where devices are accessed by names rather
than IP addresses, you will want to put in an alternate DNS (*DNSUSER) where
that domain is updated, such as the IP Manager server the remote modem is
using or the listing of IP addresses to names is kept.
If you need to manually configure DNS, in AceManager, select DNS .
