I am trying to get the authoritative DNS servers for a server in Europe per my assignment instructions. I looked up how to do it and got two different ways.
nslookup -type=soa ox.ac.uk
And the other is:
nslookup -type=ns ox.ac.uk
Both give me this for the authoritative answer part:

At first I thought it might be a security feature on Oxford's part that perhaps they hide their DNS address from nslookup so as to avoid attacks on those servers. But I learned that's a dumb conclusion and I tried those commands with every university that Google gave me for "university in Europe", and all of them gave me non-responses for authoritative answers. Am I entering the wrong command, is my computer messed up, or is it my ISP that is messing me up?
Full command and output here:
