I was told NSLOOKUP uses ptr records not A host records in
DNS. When I run debug and query a name I see =>

QUESTIONS:
blabla.blabla.com.bla.NET, type = A, class = I

Clearly I am getting an A record ???
 
Hi Mark,

I believe what you told is when you type "nslookup" at a command prompt,
it defaults to the DNS Server you are configured to.

It performs a reverse lookup for that IP address and displays it like the
following:
Default Server: UnKnown

Address: xxx.xxx.xxx.xxx

but if I use nslookup as follows, not using an ipaddress
but a name query ie.

nslookup
myserver.home.msft
Click to expand...

it must look at the Forward zone??
where does it resolve the name ?

Hi Mark,

When you start nslookup, it does a reverse lookup for the DNS server IP
address that your client is configured to use. After that it uses forward
lookups to resolve names to IP addresses and reverse lookups to resolve IP
addresses to names.

I understand now. NSLOOKUP uses reverse lookup to get to
the DNS server only, not in returning the results.
When I see the A record when debug is running that is just
that a result of my query.

Thank You, now I can sleep..
