Dynamic DNS

Dynamic DNS allows an AirLink gateway's WAN IP address to be published either
to a proprietary Sierra Wireless dynamic DNS service called IP Manager, or to a
3rd party DNS service.
Whether you have one Sierra Wireless AirLink gateway or multiple devices, it can
be difficult to keep track of the current IP addresses especially if the addresses
are not static but change every time the devices connect to the mobile network. If
you need to connect to a specific gateway, or the device behind it, it is much
easier when you have a domain name (mypage.mydomain.com).
Reasons to Contact or Connect to a Device:
• Requesting a location update from a delivery truck
• Contacting a surveillance camera to download logs or survey a specific area
• Triggering an oil derrick to begin pumping
• Sending text to be displayed by a road sign
• Updating the songs to be played on a juke box
• Updating advertisements to be displayed in a cab
• Remote accessing a computer, a PLC, an RTU, or other system
• Monitoring and troubleshooting the status of the gateway itself without
needing to bring it in or go out to it.
A dynamic IP address is suitable for many Internet activities such as web
browsing, looking up data on another computer system, for data only being sent
out, or for data only being received after an initial request (also called Mobile
Originated). However, if you need to contact the AirLink gateway directly, a device
connected to the AirLink gateway, or a host system using your AirLink gateway
(also called Mobile Terminated), a dynamic IP will not give you a reliable address
to contact (since it may have changed since the last time it was assigned).
Domain names are often only connected to static IP addresses because of the
way most domain name (DNS) servers are set-up. Dynamic DNS servers require
notification of IP Address changes so they can update their DNS records and link
a dynamic IP address to the correct name.
• Dynamic IP addresses are granted only when your AirLink gateway is
connected and can change each time the gateway reconnects to the network.
• Static IP addresses are granted the same address every time your AirLink
gateway is connected and are not in use when your gateway is not connected.
