This is mainly a place-holder file to help divide up the long list of whois-server site names.... The COM domain mostly includes organizations based in the United States. RFC 1032 had this to say about these domain names: "COM" is meant to incorporate subdomains of companies and businesses. The site names are organized alphabetically by the domain name of the whois-server machine, considering the labels (the individual components of the name, separated by dots) in reverse order. For example, FOO.AAAA.COM, BAR.AAAB.COM, BAZ.AAAB.COM, etc. .
