You could theoretically set a TTL as low as one second. However, most sites use a default TTL of 3600 (one hour). The maximum TTL that you can apply is 86,400 (24 hours).Technically, you can set any TTL value between the minimum and maximum parameters. Later in this article, we’...

The TTL values 255, 254, and 253 indicate that the lifetime of a BFD packet is 255, 254, and 253 respectively. From V200R001C01, you can configure a global TTL for a BFD session. By default, the lifetime of a static single-hop or dynamic single-hop BFD pa...
Here is an example of an A record: example.comrecord type:value:TTL @ A 192.0.2.1 14400 The "@" symbol in this example indicates that this is a record for the root domain, and the "14400" value is the TTL (time to live), listed in seconds. The default TTL for A records is 14...

| 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....
Time to live (TTL) is the length of time or “hops” that a packet may move through a network before being discarded by a router, or how long content or a query is retained in DNS and CDN caching. As you learn what TTL means, you must differentiate between Domain Name System (DNS)...
