You can query MX records in the same way. Using an ANY type, all resource records associated with a given name are returned.
> Set type = MX
> Unc.edu
Non-authoritative answer:
Unc.edu preference = 10, mail exchanger = lambada.oit.unc.edu
Lambada.oit.unc.edu internet address = 152.2.22.80
Authoritative answers can be found from:
UNC. EDU nameserver = SAMBA. ACS. UNC. EDU

SAMBA. ACS. UNC. EDU internet address = 128.109.157.30
In addition to debugging, an actual application of nslookup is to obtain the current list of root name servers for the named. ca file.
You can query all NS type records related to the root domain:

The network address is allocated by the Internet authority (InterNIC) to ensure the global uniqueness of the network address. The host address is assigned by the system administrator of each network. Therefore, the uniqueness of the network address and the host address in the network ensure the global uniqueness of the IP address.
