一个INTERNET地址是一组数字或字母。如:123.331.45.67或[email protected]。一台计算机用它来定位另一台计算机。 INTERNET地址更象一个邮政地址,一个邮政地址通过街道/公寓/楼层/单元号码/城镇/州来确定地理位置,INTERNET地址则通过计算机的名称,一个或多个域名来确定一个计算机网络的位置。计算机名象是模拟一个公寓、楼层、单元号码,而域名,通常也包含子域名,则充当街道和城镇的角 An Internet address is a group of numbers or letters. Eg 123.331.45.67 or [email protected]. A computer uses it to locate another computer. The Internet address is more like a postal address, a postal address is determined by street / apartment / floor / unit number / town / state, and the Internet address is determined by computer name, one or more domain names to determine the location of a computer network. The computer name simulates an apartment, floor, unit number, and the domain name, which usually also contains subdomains, serves as the corner of a street and town
