Recognise a documented privacy mechanism
RFC 8981 describes temporary IPv6 addresses with randomised interface identifiers for stateless address autoconfiguration. Changing those addresses over time reduces the period over which simple address based activity correlation is possible. Consequently an administrator can see different source addresses from the same host across time. Counting every distinct IPv6 string as a separate physical viewing device would be an unsupported shortcut.
Build a time bounded comparison
For an original private diagnostic exercise, record the computer interface state and the relevant application observation at the same time, then repeat after the documented addressing behaviour changes. Keep the timestamps and address roles, rather than comparing two unlabelled screenshots from different days. A new address could have several explanations; the point is to check the mechanism actually enabled on that host before drawing a device count conclusion.
Do not confuse privacy layers
Temporary IPv6 addressing and a randomised wireless MAC address concern different identifiers. Neither automatically makes an account anonymous or removes application tracking. Avoid disabling privacy features merely to make a support list visually shorter. If a legitimate service policy depends on network identity, request its documented interpretation rather than assuming an address count equals a screen allowance. This article describes a standard mechanism and does not establish which options a particular television or UK IPTV account uses.
