The Time-To-Live (TTL) for a DNS record is a value that specifies how long a resolver should cache the record. This value is set by the DNS server that is responsible for the record, and it is specified in seconds.
To see the TTL for a DNS record, you can use the dig command. This command allows you to query DNS servers for information about a specific domain.
To see the TTL for a DNS record, use the dig command with the +time=ttl option, where ttl is the number of seconds that you want the resolver to cache the record:
dig +time=ttl example.com
This will show the DNS record for example.com, along with the TTL value. For example:
