IP Manager and DNS
*DOMAIN: The domain name to be used by the modem.
*IPMANAGER1 and *IPMANAG
ER2: The IP address or domain name of the dynamic DNS
server which is running IP Manager.
*IPMGRUPDATE1 and *IPMGR
UPDATE2: How often, in minutes, you want the address
sent to IP Manager. If this is set to zero, the modem will only send an update if the IP address
changes (example, if your Raven modem is reset or is assigned a different IP address).
*IPMGRKEY1 and *IPMGRKEY
2: User defined password key which is used instead of Air-
Link secret key.
Restrictions for Modem Name
For the Modem Name, you should use something which is unique but also easy to remember. Your
company name or the intended function of the modem are recommended. If you have more than
one modem and want to name them the same, you can append a number for each. Since it is an
Internet domain name, there are some restrictions for the name.
• Must begin with a letter or number
• Can include a hyphen (-)
• Cannot contain spaces
• Must be no longer than 20 characters total
Eairlink.com
As a service, Airlink maintains a IP Manager servers which can be used for any AirLink modem.
• *DOMAIN: eairlink.com
• *IPMANAGER1 : edns2.eairlink.com
• *IPMANAGER2 : eairlink.com
DNS: Using Names Instead of IP addresses
The Raven 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 configu-
ration options requiring IP addresses. This is important if yo
ur Raven 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 Raven using IP Manager).
Note: To use the name here instead of the IP, you need to have DNS set up in your
Raven (page 17).
Note: The IP Manager service from AirLink is currently not a guaranteed service
though every effort is made to keep it operational 24/7.
When using AirLink’s IP Manager servers, since there are
many AirLink modems
using the service, it is even more imperative to have a unique name for your
modem.
