Recognise the particular address range
RFC 3927 describes automatic IPv4 link local configuration in the 169.254/16 prefix when ordinary address configuration is unavailable. Its purpose is useful communication with devices on the same physical or logical link. This is a distinct category from the familiar private address supplied by many home routers. Seeing an address in a network screen is therefore not enough to conclude that ordinary routed internet configuration has succeeded.
Compare the expected configuration
For an original diagnostic scenario, a computer normally receives a router managed private address but now displays a 169.254 address on the relevant adapter. Record the adapter and how addressing is configured, then check the intended local connection and the router own DHCP status through its documented interface. Do not copy a neighbour device address as a quick manual substitute. The observed range narrows the configuration question without proving why normal configuration was unavailable.
Keep local success in its scope
Two compatible devices on the same link may still communicate using link local addressing, while an external service remains unreachable by that path. Those outcomes are consistent with the address scope. A successful local transfer does not establish a working internet route, and a failed remote player login should not immediately trigger password replacement before the network state is understood. The standard does not establish any UK IPTV address policy or diagnose a particular router from the address alone.
