The man here says querytype=value

nslookup versions vary a lot! I recall using debug level 2 was interesting, as it shows the flow

Using KLOTH.NET (as I am behind firewalls):
Code:
 here is the nslookup result for unix.com from server localhost, querytype=ANY :
 
DNS server handling your query: localhost
DNS server's address:    127.0.0.1#53
 
Non-authoritative answer:
unix.com
    mail exchanger = 1 ASPMX.L.GOOGLE.com. unix.com
    mail exchanger = 5 ALT1.ASPMX.L.GOOGLE.com. unix.com
    mail exchanger = 5 ALT2.ASPMX.L.GOOGLE.com. unix.com
    mail exchanger = 10 ASPMX2.GOOGLEMAIL.com. unix.com
    mail exchanger = 10 ASPMX3.GOOGLEMAIL.com. unix.com
    mail exchanger = 10 ASPMX4.GOOGLEMAIL.com. unix.com
    mail exchanger = 10 ASPMX5.GOOGLEMAIL.com. unix.com
     origin = ns1.linode.com
     mail addr = webmaster.unix.com
     serial = 2011020734
     refresh = 7200
     retry = 3600
     expire = 604800
     minimum = 3600
 Name:    unix.com
 Address: 81.17.242.186 unix.com
    nameserver = ns1.linode.com. unix.com
    nameserver = ns2.linode.com. unix.com
    nameserver = ns3.linode.com. unix.com
    nameserver = ns4.linode.com. unix.com
    nameserver = ns5.linode.com.

Most of the goodies you want are in SOA:

  [ Query 2 of max 100 ]
NSLOOKUP is a service to look up information in the DNS (Domain Name System [RFC1034, RFC1035, RFC1033]). The NSLOOKUP utility is a unix tool. If you want to learn more, here is the nslookup manual (man page).
Basically, DNS maps domain names to IP addresses.
Although this web online service can query a specific DNS server, in most cases it may be sufficient and convenient just to use the KLOTH.NET default nameserver "ns.kloth.net" or "localhost"/127.0.0.1.
To resolve an IP address by reverse lookup (get a computer's name if you only have its IP address), try to perform a PTR query instead of ANY. This reverse lookup will only work if the IP address owner has inserted a PTR record in the DNS. The PTR information is informal only and it may mostly be true, but sometimes not. If you don't get a PTR information about a specific computer from a NSLOOKUP query, you may want to try our whois service to find out the owner of this IP address.
Like the PTR, other records are also not mandatory: LOC, RP, TXT. They are not strictly required in the DNS and their content may be true or not.
You can't trust on the LOC to locate a host, because most hosts don't have this record defined. 
 
If you prefer dig over nslookup, you may try our dig service.
