Question: Does Chrome Incognito mode always prefer mDNS candidates? (v140)

[jinyun]

Hello,

My Chrome version is 140.0.7339.128.
When running in Incognito mode and connecting to my server via a public IP address, I observed that ICE gathering only produces mDNS host candidates.

In contrast, under similar conditions in normal browsing mode, I sometimes see raw IP host candidates (for example, when testing with private IPs or localhost).

My question is:
👉 Is there a specific policy in Chrome that makes Incognito mode prefer (or enforce) mDNS candidates compared to normal mode?
👉 If yes, is this behavior documented anywhere?

Thanks a lot for any clarification.
