Top VPN providers offer IPv6 leak protection implemented in their applications, but it is safer to disable IPv6 from your machine. The problem is that, if your network supports IPv6 and the VPN server you are connected to works over IPv4, then your IPv6 traffic may leak. Consequently, most VPN services do not support IPv6 VPN tunnels. Thus, many Internet services (data centers, Internet Service Providers) still use IPv4 and do not assign public IPv6 addresses.
