Just came across the guide on vpn leaking thank god, purevpn wasn't leaking my ip. I read at their blog so thought to share if any of you are using a any vpn service then do give it a go.
Disconnect the vpn is you are connected
Note down your ip address from the What is my IP
Then connect the vpn
check the ip again from the what is my ip tool
if the ip before and after connection are same then it means that your vpn is leaking your ip address and its time to get a new one or the refund.
