What does DNS time to live mean?
A DNS record's time to live, or TTL, indicates how long a cached answer can generally be retained before it needs refreshing under normal DNS behaviour. It helps balance caching and change propagation. It is not the subscription's remaining duration.
Why it matters
A service moving addresses must account for cached answers, while the viewer usually has little control over the authoritative record. Changing a player setting cannot rewrite the provider's DNS TTL. If a migration is suspected, verify the current supported hostname and use documented local troubleshooting. Avoid claiming that every device worldwide updates at exactly the same second.
A practical example
Two clients can temporarily obtain different answers during an address change because their cache histories differ. A short wait or supported fresh lookup may help, but a persistent wrong endpoint still needs provider attention.
