How does browser gather local IPv6 address to add to SDP?

[jbust...@broadsoft.com]

Hi,

Even that I have an IPv6 (not link-local) address assigned to my network interface and I have connectivity, I am not able to get browser to add ICE candidates for that IPv6 address in SDP. 

IPv4 candidates are generated as expected.

Does anyone know how these ICE candidates are decided/detected? Or give some hints on what I could be missing?

Regards,

Hi Jorge,

Is the behavior the same in Firefox and Chrome?

By the way, Chrome will only enumerate all network interfaces if "getUserMedia" permission has been granted (to prevent data-only applications from scraping IP addresses). So it's possible you're running into that.

Otherwise, I'm not sure. Here's where network interfaces are enumerated in chromium: https://cs.chromium.org/chromium/src/net/base/network_interfaces.h

And here's where webrtc is possibly filtering them out: https://cs.chromium.org/chromium/src/third_party/webrtc/rtc_base/network.cc?q=networkmanagerbase&dr=CSs&l=115
