About this tag
The ipv6 privacy tag covers how IPv6 addressing can affect the visibility and lifetime of network identifiers. Tagged discussion examines the shift away from older EUI-64 addresses that could expose a MAC-derived device fingerprint, the privacy implications of household prefixes that remain stable, and the risks of VPN or router configurations that allow IPv6 traffic to bypass expected protections. It also covers RFC 8981 and the reduction of IPv6 temporary address lifetimes to two days. The focus is practical rather than alarmist, with relevant considerations for Windows users and network administrators evaluating modern IPv6 privacy assumptions.

    RFC 8981 Cuts IPv6 Temporary Address Lifetime to 2 Days

    IPv6 can expose more durable network identifiers than many users expect because early EUI-64 addressing embedded a device’s MAC-derived fingerprint, household prefixes may remain stable, and poorly designed VPN or router configurations can let IPv6 traffic bypass privacy assumptions even on...
