WHOIS

In this lab we are asked to perform a WHOIS lookup against paypal.com domain and lookup for the registrar Internet Assigned Numbers Authorizy (IANA) ID number.

All we have to do is enter the command whois paypal.com | grep -i iana

And we get the IANA ID: 292

For the second part it ask what is the email contact for the tesla.com domain.

With the command whois tesla.com | grep -i admin we can easily filter what we are looking for. The contact is [email protected]
