The dig command can be used to find out the Time to Live (TTL) value for DNS records. The TTL value is the amount of time in seconds that a DNS record will be cached on a local DNS resolver before it needs to be refreshed.
Here’s how you can use the dig command to find the TTL value for a specific domain name:
dig <domain name> +nocmd +noall +answer
Replace <domain name> with the domain name that you want to look up.
For example, to find the TTL value for the domain www.example.com, you would run the following command:
dig www.example.com +nocmd +noall +answer
The output of the command will show the TTL value in the “TTL” field for each DNS record associated with the domain name.
Note: The +nocmd option is used to prevent the dig command from showing the full command line and version information, while the +noall option is used to show only the relevant information, and the +answer option is used to show the DNS answers.
