What does IP fragmentation mean?
Fragmentation divides an IP packet into pieces to fit a smaller transmission limit where the protocol permits it. Behaviour differs between IPv4 and IPv6, and path-MTU mechanisms also matter. Fragmentation is not something a viewer should tune by guessing from a buffering spinner.
Why it matters
An administrator may investigate packet size when specific destinations or large transfers fail reproducibly. Ordinary users should start with supported network configuration, valid server details and a controlled local comparison. Changing packet sizes without a diagnosis can create additional overhead or compatibility issues. A media codec and an IP packet are also different layers; renaming a stream format does not change the network's packet handling.
A practical example
If a service works directly but fails through one tunnel, report that controlled difference and the tunnel's documented configuration. It is a clue, not proof that fragmentation is the sole cause.
