OEM - What IP addresses should I allow through my firewall?
As of May 2019, OEM server was migrated to Azure servers hosted in the US. Below are the IP addresses used by OEM server. Integrators will need to white list the IPs shown under "Device Data from OEM server to Software Platforms" to ensure that data can make it through their firewall.
|Traffic Type||DNS Entry||IP Address|
|Device to OEM Server
(Incoming device data)
|External parties to OEM Web
API and Website
(Incoming HTTP traffic)
|Device Data from OEM Server
to Software Platforms
(Outgoing device data from
OEM, incoming to Software
|Firmware/Aiding Data files hosted on OEM
OEM hosts some files needed by different devices
(same for all 3 DNS entries)
uBlox Aiding Data
|Server Description||DNS Entry|
The device will also periodically connect in to the uBlox servers, so these entries should be white listed also.
The IP addresses frequently change so it is important to add the DNS entry
Location Engine does not use Static IP addresses (even though it is an extension of OEM server).
Location Engine is hosted on Azure's ‘East US’ servers. The IP addresses used by these servers can be found here.
