**time-to-live**

The **time-to-live (TTL)** tag is used to categorize content related to the lifespan or expiration of data in computing and networking contexts. TTL commonly refers to the duration or number of hops that data packets, cache entries, DNS records, or other temporary information are considered valid before they are discarded or refreshed. Use this tag for posts discussing TTL concepts, configurations, and best practices in areas such as network protocols, caching mechanisms, and data management.
