The question asks: "Run nslookup so that one of the DNS servers obtained in Question 2 is queried for the mail servers for Yahoo! mail. What is its IP address?"

I did what is said and for some reason, I'm getting a query refusal. Does anyone know what's the problem? Thanks.

I was getting this error myself as well I think it's the way you are executing the command

i just switched it up stating

nslookup *nameofserver* mail.yahoo.com

and it worked fine, although I don't know why order would matter

Well it says that the syntax is: nslookup –option1 –option2 host-to-find dns-server

I would think the order matters since switching it would make mail.yahoo the dns-server and dns0.eng.cam.ac.uk the host-to-find.

Even when I flipped the two, I didn't get anything.

Apparently there's a return if you insert a - before mail.yahoo.com => -mail.yahoo.com

Try that.
