引言

互聯(lián)網(wǎng)是一個(gè)基于開(kāi)放互聯(lián)協(xié)議的網(wǎng)絡(luò)，域名是互聯(lián)網(wǎng)上的基礎(chǔ)服務(wù)，是用于識(shí)別和定位互聯(lián)網(wǎng)上

計(jì)算機(jī)的層次結(jié)構(gòu)式的字符標(biāo)識(shí)，與計(jì)算機(jī)的互聯(lián)網(wǎng)地址相對(duì)應(yīng)。基于域名可提供WWW、EMAIL、

FTP等應(yīng)用服務(wù)。

實(shí)現(xiàn)對(duì)中文域名的支持首先需要實(shí)現(xiàn)對(duì)國(guó)際化域名的支持。本文件引用的IETFRFC3490和IETF

RFC5890是國(guó)際化域名的標(biāo)準(zhǔn)。IETFRFC3743是針對(duì)中日韓的文字字符存在異體的問(wèn)題而設(shè)計(jì)的。

本文件的第4章主要對(duì)應(yīng)IETFRFC3490和IETFRFC5890，主要規(guī)定了如何在應(yīng)用程序中實(shí)現(xiàn)對(duì)中文

域名的支持。本文件的第5章主要對(duì)應(yīng)IETFRFC3743，主要規(guī)定了中文域名的注冊(cè)指南。要實(shí)現(xiàn)對(duì)本

文件的支持，亦可直接參照IETFRFC3490和IETFRFC3743。

隨著互聯(lián)網(wǎng)的發(fā)展，中文用戶的數(shù)量不斷增加，對(duì)于中文域名的使用需求也在增加。但是中文域名

和傳統(tǒng)的英文域名有較大差別，比如：域名字段分隔符（中文句點(diǎn)和英文句點(diǎn)）不同，中文字符有多種

形式（包括簡(jiǎn)體、繁體、異體、古體等）；并且中文域名的字符集比傳統(tǒng)的英文域名的字符集大很多。

為了規(guī)范中文域名的使用，讓中文用戶能夠方便地通過(guò)中文域名來(lái)使用互聯(lián)網(wǎng)的各種應(yīng)用服務(wù)，盡快制

定中文域名標(biāo)準(zhǔn)，進(jìn)而推動(dòng)中文域名的使用是十分重要的。
