| > NAT punching definitely tells other peers your NAT's IP address Yes, and that's all you share, so when the NAT is shared with other people (like other students on a campus for instance, or other customers of your phone mobile phone carrier) the amount of info that can be collected is much lower than if you have a public IP address for your computer. > Unless you're behind CGNAT Did you read what I wrote above, when I said: “at least when we're talking about a NAT you share with other people, not just your ISP box's NAT”. > (and often your local address too, but that's less important). Here you're mixing up the hole-punching part with the signaling protocol (ICE, which have had this issue in the past, before browsers switched to mDNS[1] instead of private IP addresses in ICE candidates).
