什么是域名？
　　 域名：如“〞的形式。它同IP地址一样，都是用来表示一个单位、机构或个人在网上的一个确定的名称或位置。所不同的是，它比IP地址较有亲和力，容易被人们记记和乐于使用。
　　 由于国际域名资源有限，各个国家，地区在域名最后都加上了国家的标识段，由此形成了各个国家，地区自己的国内域名。国别的最高层域名：.cn-中国；.au-澳大利亚；.jp-日本等。
　　 另外，不同的组织、机构，都有不同的域名标识，如：.com-商业公司；.org-组织、协会等；.net-网络效劳；.edu-教育机构；.gov-政府部门；.mil-军事领域；.arts-艺术机构；.firm-商业公司；.info-提供信息的机构等。
