Question -   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
www.yahoo.com

Name:    www.yahoo.akadns.net
Addresses:  64.58.76.227, 64.58.76.228, 64.58.76.229, 64.58.76.176
           64.58.76.177, 64.58.76.178, 64.58.76.179, 64.58.76.222,
64.58.76.223
           64.58.76.224, 64.58.76.225
Aliases:  www.yahoo.com


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