What is TTL in DNS, and how should I set it?
TTL, or Time to Live, defines how long DNS records are cached by servers. A shorter TTL means faster propagation of changes but results in more frequent DNS lookups, which can increase server load. A longer TTL reduces server load but may delay updates when you change DNS records. The standard TTL setting is 14400 seconds (4 hours), which offers a balanced approach. Choose a TTL based on how often you expect to update your DNS settings.
