Question : Query Authoritative DNS Servers

Hi there, I have around 100 domains and I need to query and list the authoritative nameservers for all of them, is there a quick way to do this instead of going to www.who.is and querying each domain name one by one?

Answer : Query Authoritative DNS Servers

With this script you get the authorative name servers of the domains. But you could also use whois (the linux utility called that name) and do a grep for the Nserver line. Both will give you the same result.
