It's the TTL of the record in the public DNS, how the record is registered there is important. The record seems to have a TTL of 5 minutes, you can cache all you want... But it the public record has a TTL of 5 minutes and it changes, then it would be nice if you received that updated record instead of trying to keep on to a possibly outdated record ;)
