Global IPv6 adoption reached approximately 45% in 2024, yet many VPN providers still do not fully support IPv6 traffic tunneling. — Google IPv6 Statistics (2024)

IPv6 leaks occur when a VPN tunnels only IPv4 traffic while allowing IPv6 requests to bypass the encrypted tunnel entirely. — Internet Engineering Task Force (2024)

Dual-stack networks (supporting both IPv4 and IPv6) are present in over 60% of major ISP networks worldwide, increasing IPv6 leak risk. — APNIC (2024)

Each IPv6-capable device can have multiple unique addresses, making IPv6 leaks potentially more identifying than IPv4 leaks. — RIPE NCC (2023)
