So I'm working on this question: 

2. Run nslookup to determine the authoritative DNS servers for a university in Europe.

When I put in the command, I don't see any authoritative DNS servers popup. This is what I get

Ashleys-MacBook:~ ashleyvo$ nslookup -type=NS ox.ac.uk

Server: 192.168.0.1

Address: 192.168.0.1#53

 

Non-authoritative answer:

ox.ac.uk nameserver = ns2.ja.net.

ox.ac.uk nameserver = dns0.ox.ac.uk.

ox.ac.uk nameserver = dns2.ox.ac.uk.

ox.ac.uk nameserver = dns1.ox.ac.uk.

 

Authoritative answers can be found from:

Is it different on the mac?  Should I look at the IPs of these nameservers?
