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.
