Question about network interface at runtime

[advancenXX]

I am aware of the Dynamic-network-interface feature so that I can invoke set_qos() when a new network interface is enabled.
But I am not sure if it can work well as it is still under development.

And I am also wondering if it is possible to pass a STATIC IP to fastdds before this network interface is enabled. My network interface is fixed so that I want to set it to fastdds at an earlier time.

Dynamic network interfaces work for UDPv4. There is a known issue that if initially no network interface is enabled, even if a network interface is included afterwards, communication is not established.

Concerning the static IP address, you can try to configure the default unicast locator list with that specific address so the locators announced to the remote participants are exclusively those on your static IP.
