There are commands which one can use to resolve a domain name to an IP address, and vice versa. There is also a command or means to determine if a domain name is registered, and if so, to whom. Where can I find a list of such commands?

Paul this is a great question,

To answer your question I will be making the assumption that you are using Windows NT, 2000 or XP. To find out what domain name is registered to a given IP or even series of IP's use the command NSLOOKUP followed by the domain you want to look up. Basically this is a query to your DNS server, a DNS (Domain Name System) is a central repository or database of the association of IP's to domain names. Here is the result of a NSLOOKUP on




Here is a great site that will give you a list for all the TCP/IP commandsthat Microsoft supports. nol/winxppro/proddocs/tcpip_utils.asp
