Vista - DNS Query with WSH

Hi all,

I am trying to analyze web server's log and need to convert
IP addresses in the log into human-readable host name.

I need to write a script that accepts IP addresses from STDIN or
somewhere else, and prints correspobnding FQDN. For instance,
it should read an IP address '61.211.239.46' and write
'sodans.usata.org'.

I am now capturing NSLOOKUP's output, but it is not smart because
there are considerable overhead of calling NSLOOKUP.EXE for each
IP address.

So I have a question: is there any smart and fast method to do a
DNS query on WSH (JScript/VBScript)?

I am working on Windows XP Pro and Vista Business, both 32-bit
Japanese edition.

Thanks in advance.

One possibility is here:

www.jsware.net/jsware/scripts.php5#jshttp

The download is a component that, among other things,
does IP -> Hostname conversion. There's also a pre-
written script included (IPInfo.vbs) for processing server
logs. It uses both hostname resolution and a free database
to convert something like:
100.100.100.100
to something like:
server123.somewhere.com - Akron-OH-US

The component must be registered on the system but has
no dependencies. It uses the Windows sockets API directly.

I have no experience with STDIN. I'm not sure how that
would fit with this component. The IP processing script is
just a drag-drop operation. You edit the script to accomodate
your server log format. Then drop a log onto the script. The
script then generates a duplicate log with the IP numbers
replaced by hostname-location.

Thanks, mayayana.

I have to tell one more restriction: the script file must be portable
and available to non-Admin users. Therefore, I must avoid registering
a new OCX component to the system.

If I am allowed to distribute a pair of large files, I would use
perl's built-in gethostbyaddr() function. It requires PERL.EXE and
PERL58.DLL be distributed together. If a DNS query can be done by
WSH, I will no longer need to distribute those large files....

Thanks hth, it worked envn on Windows 98 which does not have nsloopup.exe.
