Time to live (TTL) determines how long to cache either a query or content. Learn how time to live (TTL) works & how it impacts your website.
| TTL definition Time to live (TTL) refers to the amount of time or “hops” that a packet is set to exist inside a network before being discarded by a router. TTL is also used in other contexts including CDN caching and DNS caching....

The TTL field limits packet lifetime in computer networks and IP packets to prevent routing issues. The TTL should be set high enough to allow packets to reach their destination while avoiding too many hops. Network engineers optimize TTL based on topology, reliability requirements, and application...
Time to live (TTL) is a value that defines the amount of time that a data packet or record should exist on a network, computer or server before it is discarded.
TTL: an 8-bit field indicating a time to live (TTL) value. This field is the same as the TTL field in IP packets. An MPLS label is encapsulated between the link layer and network layer (also referred to as Layer 3). The following figure shows where an MPLS label is encapsulated in...
When you set TTL values for your website, you choose a value in seconds. For example, a TTL value of 600 is the equivalent of 600 seconds or ten minutes.The minimum available TTL is usually 30, equivalent to 30 seconds. You could theoretically set a TTL as low as one second. However...
Time-to-Live (TTL) is a powerful concept used across various computing fields, from networking to data management. Like any technology, it comes with its own set of advantages and disadvantages that affect system design and performance. Understanding these can help optimize its use to achieve the...
Validity check and discarding of packets that do not need to be processed Invalid ICMP packets, such as the packets whose TTL is 0 and ICMP types are 15, 16, or 17 are discarded directly. You can also configure the function of discarding the ICMP packets that are seldom used, including ...
DNS caching can lead to uneven traffic distribution if not managed correctly. Some DNS resolvers cache IP addresses for a specific duration (TTL), potentially directing traffic to a less optimal server until the cache expires. From DNS caching nuances to managing TTL settings and the crucial aspe...
