What is the TTL value?
Time-to-live (TTL) is a value in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded.

What is TTL 64?
TTL is Time To Live. Each hop decrements this field by one, and if it reaches 0 it is dropped (usually this happens only in loop situations). This makes sure that data packets are not congesting a network if there is a IP routing loop present. … 64 is the number of hops that the packet can travel before it is dropped.
What is TTL value in MX record?
Each of your domain’s DNS records, such as an MX record, CNAME record, and so on, has a TTL value. A record’s current TTL determines how long it will take any change you make now to go into effect. Changes to a record that has a TTL of 86400 seconds, for example, will take up to 24 hours to go into effect.
What is the lowest TTL setting?
TTL is set in seconds, and the lowest value possible is 600 seconds (10 minutes). The highest possible value is 86400 seconds (24 hours). If you leave the field empty, the default value is 3600 seconds (1 hour).

What is DNS record TTL?

Is higher TTL better?
In the event of needing to quickly change the record, a higher TTL can result in longer than expected change propagation to all recursive servers. For records that leverage an advanced traffic management configuration—such as NS1’s Filter Chain—it’s best to keep the TTL as short as possible.
