TTL (Time to Live)
A DNS setting that determines how long information is cached before being refreshed, affecting how quickly changes propagate across the internet.
TTL, or Time to Live, is a setting in your DNS records that controls how long information is cached before refreshing. A shorter TTL ensures changes, such as new IP addresses or record updates, spread quickly across the internet. A longer TTL reduces the number of DNS requests, improving efficiency and stability. The ideal value depends on how often you update your DNS. For websites that rarely change, a longer TTL saves bandwidth, while dynamic setups benefit from shorter values. Understanding and adjusting TTL is key if you want to balance flexibility and reliability in your hosting configuration.
