你知道吗?就象我们每个人都有自己的家一样,因特网上也存在地址和门牌号。随着互联网的不断发展,这种地址也经历了一系列的进化和变迁,大致可分为三个阶段:IP地址、域名和中文网址。最初,为了区分网络上的每一台主机,设立了IP地址。它由4部分数字组成,每部分都不大于256,各部分之间用小数点分开,如202.123.107.18。像大家知道的“新浪网”,其主机IP地址就是202.106.184.200。对于普通用户而言,记忆这一串串繁琐枯燥的数字实在太困难,如果能用比较简单的语言来表示网址就好了。第二阶段的域名,正是在这个基础上产生的。城名都是英文字母或单词的组合,比起IP地址,域名
Did you know? Just as each of us has our own home, there are addresses and house numbers on the Internet. With the continuous development of the Internet, this address has undergone a series of evolution and changes, which can be roughly divided into three phases: IP address, domain name and Chinese website. Initially, in order to distinguish between each host on the network, set up an IP address. It consists of four parts of numbers, each part is not greater than 256, separated by a decimal point between the various parts, such as 202.123.107.18. As we all know “Sina”, the host IP address is 202.106.184.200. For ordinary users, remember this string of complicated numbers boring is too difficult, if we can use a relatively simple language to represent the URL just fine. The second phase of the domain name, it is on this basis. City names are English letters or a combination of words, compared to the IP address, domain name
