 # openpyn
-A python3 script to easily connect to and switch between, OpenVPN servers hosted by NordVPN. Quickly connect to the least busy servers (by grabbing current data from Nordvpn's website) and the ones that have the lowest latency from you. It Tunnels DNS traffic through the VPN which normally (when using OpenVPN with NordVPN) goes through your ISP's DNS (still unencrypted, even if you use a thirdparty) and completely compromises Privacy!
