Notes on Nslookup
-----------------

Nslookup is a simple application that does one of two things:  either it
looks up an IP address for a domain name, or it looks up a domain name for
an IP address.  It did not come with any documentation.

To set it up, edit file WATTCP.CFG.  If you already have a working
WATTCP.CFG from another application, you can just make this file a single
include line pointing to that one, like so:

   include=e:\internet\wattcp.cfg

Otherwise, load WATTCP.CFG into your favorite text editor.  If you have
static IP, fill in your static IP address on the my_ip line:

   my_ip=204.117.9.33

(For me.)  If you have dynamic IP, comment out that line and put an include
line like this instead:

   include=e:\internet\ipaddr.cfg

You will have to create IPADDR.CFG at connect time and give its pathname
here; see file README on my site.

Leave the netmask line alone.  Do *not* fill in your real netmask.

If you have a static gateway, fill in its IP address on the gateway line:

   gateway=199.191.1.70

Otherwise, if your gateway is dynamic, either give the gateway you *usually*
get, or comment out the gateway line and put this instead:

   include=e:\internet\gateway.cfg

You will have to create GATEWAY.CFG at connect time and give its pathname
here; again, see README.

Fill in the IP address of your nameserver:

   nameserver=199.191.1.80

(Example.)

To use the program to look up the IP address for a domain name, give the
domain name on the command line:

   E:\INTERNET\NSLOOKUP>nslookup ftp.agate.net
   ftp.agate.net = 199.191.1.80

To look up the domain name for an IP address, give the address:

   E:\INTERNET\NSLOOKUP>nslookup 199.191.1.80
   199.191.1.80 = service.agate.net

As you can see, Nslookup is pretty simple.  It seems that the program always
gives these error messages:

   ERROR releasing packet driver for ARP
   ERROR releasing packet driver for IP

It works fine anyway.
