VPN and linked ip


To use a VPN /WireGuard together with Nextdns on some platforms you have to use the linked IP feature, because both cannot function at the same time (eg, iOS ).
My understanding however is that multiple VPN users can have the same internet facing IP address. If user A links his IP, and later on user B links the same IP to his configuration, couldn’t that be used, voluntarily or not, by user B to view all DNS requests made by user A ? 

Have a good day

  • Both users would need to have the same source and dest IP (we allocate from a pool of IPv4 IPs for Link IP, different for each config from the same config). With enough users with same DNS IP sharing the same VPN IP, conflicts could potentially happen, but it's unlikely.
