Q: Seeing 10.x.x.x addresses in my BitTorrent client Off late, I am seeing a number of IP addresses starting with 10.x.x.x in my bittorrent peer list. Aren't these IP addresses supposed to be private ones? I don't understand how I am able to see the IP address instead of the WAN (external IP) of the client... Any one knows why?
Output:
traceroute to 10.8.73.85 (10.8.73.85), 30 hops max, 60 byte packets
 1  10.0.3.3 (10.0.3.3)  1.093 ms  0.842 ms  0.775 ms

A: If you're on some anonymising VPN, then all your outgoing and incoming internet traffic will go through that VPN. And others using that very same VPN will have IP addresses in the same private range. (To the outside world, all these users will share a single public IP address, which is not the IP address as assigned by their ISP.)
(The same might apply to using Tor, but I doubt that.)

A: It looks like that address isn't actually working, so you're probably just picking up a stray LAN address from acquired from:


*

*a silly tracker

*peer exchange with a peer which doesn't know whether or not you're on the same LAN
