All about Public Static IP

Public Fixed IP – Light France Offer

Activate a Public Fixed IP on your Light France plan, via API or directly from our SIM management platform Auriga.

What is a Public Fixed IP?

A Public Fixed IP is a unique and permanent Internet address assigned to a SIM card. Each SIM receives its own public IPv4 address, without NAT and without IP sharing. This allows remote access to connected equipment without any change of IP address.

What is a Public Fixed IP used for?

Managing M2M equipment remotely
Enabling secure connections (VPN, monitoring, remote access)
Hosting a service or server accessible from the Internet

APN used for the Public Fixed IP

When a Public Fixed IP is activated, the SIM must use the dedicated APN: data.com.
Without a Public Fixed IP, the default APN for Light offers is orange.

Network compatibility

Compatible with 3G, 4G and 5G NSA.

When should the APN be changed?

Immediately after activating the Public Fixed IP (via Auriga or API)
Before the device attempts its next data session
If the device was already connected, a reboot may be required

How to activate the Public Fixed IP

From the Auriga portal

Select the relevant SIM
Activate the Public Fixed IP option
The assigned IP address appears in the SIM dashboard
Configure the data.com APN on the device

Via API

Enable or disable the option SIM by SIM
Configure the data.com APN on the device

Availability of the option

Available for Light France offers, for M2M Advanced and M2M Start plans (bundle or pay‑as‑you‑go).

Viewing the IP address

The IP address assigned to the SIM is available in the Single IP Report (see here).

If you cannot wait for the report to be generated, the IP can be retrieved by querying the SIM from a device, even if this is not the final device in which the SIM will be used.

Coming soon: A future platform update will allow the Public Fixed IP to be displayed directly in Auriga, within the SIM information block at the top of the SIM Details page.

Actions required after activation

A device reboot may be needed if the SIM was previously connected
Ensure that the APN data.com is correctly configured on the device

Limitations

Not compatible with plans that include a data speed reduction (FUP)
Not compatible with the SDTR (Real-Time Data Supervision) option
