I.P. addresses are a set of four numbers, separated by three periods or dots. Domain Name Many had trouble remembering the numeric type of addresses, so the Domain Name addressing scheme was invented. An example would be tali.uchsc.edu . Domain names are simply an alias for IP addresses, in fact, tali.uchsc.edu and 140.226.1.10 are equivalent. Uniform Resource Locators, which are more prominent because of the World Wide Web, include a method of access and a domain name.
Some Internet sites offer information through several different types of Internet access.
Sometime, URLs include a path and a file name, as in the FTP example below. This is shorthand for saying that it's a World Wide Web site, accessible only with a Web browser. If you can determine the Web site host, connect to the host and follow your best-guess links to the file you are wanting. Watch other sources for announcements of Web site address changes. Web Masters use Newsgroups or Discussion Lists quite frequently in announcing changes to the population assumed to be most interested in the sites.
