TTL (Time to Live) is a value in DNS records that specifies how long (in seconds) a DNS resolver should cache the record before requesting a fresh copy from the authoritative nameserver. A lower TTL means more frequent lookups but faster propagation of changes. A higher TTL reduces DNS query load but means changes take longer to propagate. Common TTL values range from 300 seconds (5 minutes) to 86400 seconds (24 hours).

TTL is the time (in seconds) that a DNS record is cached by resolvers. Lower TTL means faster updates when you change records; higher TTL means less DNS query traffic.
