dig
utility as part of thednsutils
package:sudo apt-get install dnsutils
-
Check which NS servers the domain is delegated to:
dig <example.com> NS
Specify
<example.com>
as the domain name. -
Query the record data from the NS server. If the domain is delegated to multiple NS servers, repeat the request for each server:
dig <ns_server> <example.com> <type>
Specify:
<ns_server>
— The NS server you got in step 3;<type>
— record type, e.g,A
for A record. To display information about all records in the domain, specifyany

The response will contain the value of the entry and its TTL. TTL is the time in seconds during which a resource entry in the NS server cache is considered up to date and does not need to be re-cached.
