What is the animation on the left full of RFC 1918 addresses ? I assume those are really NAT-ed at some point, aren't they ?

- seba_dos1 11y agoThat's what caught my eye as well. I didn't know that was possible to get via the browser and started to think about its implications. I wonder if exposing private IP to any website is a very good idea when router firmwares have all sorts of basic security bugs in their web panels.

- jsprogrammer 11y agoWebRTC can bust through NATs with STUN and provide a TURN proxy in case the NAT can't be busted through. STUN will generate a number of candidate addresses that may be tried for initiating WebRTC connection(s). These addresses may be exchanged through a third party or directly communicated between peers once a data connection is established. It looks like the addresses in the animation are generally the local host addresses of the machines you are connected to. Perhaps the site is just showing the first candidate in the list, or, intentionally picks the local name to allow for moderate privacy.
