Description vinayak.kulkarni 2022-09-09 06:23:28 PDT 
Not seeing the address field in remote-candidate when the candidate type is "host". The same is working fine when the candidate type is "relay"

Below is the code snippet used to fetch the stats

var stats = await pc.getStats();
var selectedPair;
stats.forEach(function(stat) {
    if(stat.type === "transport") {
        selectedPair = stats.get(stat.selectedCandidatePairId);
    }
});
var localCandidate = stats.get(selectedPair.localCandidateId);
var remoteCandidate = stats.get(selectedPair.remoteCandidateId);

Please see the screenshot below

Yes, we are filtering all host local candidates since they might not always be known from the web page (in case IP addresses are replaced by mDNS).
With our mDNS libwebrtc integration, we might be able to expose this field if stats appropriately use the mDNS names when needed in stats.

Hi youenn,
Thanks for the info
Is there any work around that you would suggest to get this working for now?

Thanks,
Vinayak
