WebApr 29, 2024 · Time-to-Live (TTL) in DNS: DNS TTL refers to the time taken by DNS for caching a record. In other words, the duration for which a DNS record is to be kept or the time it takes for a DNS record to be returned from the cache is referred to as time-to-live. It is a numerical value set in a DNS record on the domain’s authoritative domain name server.
