This is mainly a place-holder file to help divide up the long list of whois-server site names.... The EDU domain mostly includes organizations based in the United States. RFC 1032 had this to say about these domain names: "EDU" was initiated to accommodate subdomains set up by universities and other educational institutions. 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.EDU, BAR.AAAB.EDU, BAZ.AAAB.EDU, etc. .
