Abstract –摘要 This document defines the format for literal IPv6 Addresses in URL’s for implementation in World Wide Web browsers. This format has been implemented in the IPv6 versions of several widely deployed browsers including Microsoft Internet Explorer, Mozilla, and Lynx. It is also intended to be used in the IPv6 version of the service location protocol. 本文档定义了在WWW浏览器的URL中执行的文本IPv6地址的格式。在包括Microsoft的 IE，Mozilla和Lynx等几个已经被广泛安装使用的浏览器的IPv6版本中，这种格式已 经被使用。并且这种格式也将被应用于服务定位协议的IPv6版本中。 This document incudes an update to the generic syntax for Uniform Resource Identifiers defined in RFC 2396 [URL]. It defines a syntax for IPv6 addresses and allows the use of “[” and “]” within a URI explicitly for this reserved purpose. 本文档包括了一个对在RFC 2396 [URL]被定义的统一资源标识符中的一般性语法的 更新。为了这个预定目标，本文档明确定义了IPv6地址的语法规则并允许在统一资源 标识符中使用“[”和“]”符号。
Introduction –介绍 The textual representation defined for literal IPv6 addresses in [ARCH] is not directly compatible with URL’s. Both use “:” and “.” characters as delimiters. This document defines the format for literal IPv6 Addresses in URL’s for implementation in World Wide Web browsers. The goal is to have a format that allows easy “cut” and “paste” operations with a minimum of editing of the literal address. 在[ARCH]中定义的文本IPv6地址的原文表述不能直接和URL的表述方法相适应。尽管 两者都使用符号“：”和“.”作为分隔符。本文档定义了在WWW浏览器的URL中执行 的文本IPv6地址的格式。其目的就是为了得到一种格式，能够很容易的使用剪切和 粘贴操作以使文本地址编辑操作达到最少。 Hinden, et al. Standards Track [Page 1] RFC 2732 IPv6 Literal Addresses in URL’s December 1999 The format defined in this document has been implemented in the IPv6 versions of several widely deployed browsers including Microsoft Internet Explorer, Mozilla, and Lynx. It is also intended to be used in the IPv6 version of the service location protocol. 在包括Microsoft的IE，Mozilla和Lynx等几个已经被广泛安装使用的浏览器的IPv6 版本中，这种格式已经被使用。并且这种格式也将被应用于服务定位协议的IPv6版本 中。 1.1 Requirements 要求 The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, if and where they appear in this document, are to be interpreted as described in [KEYWORDS]. World Wide Web browsers SHOULD implement the format of IPv6 literals in URL’s defined in this document. Other types of applications and protocols that use URL’s MAY use this format. 如果本文档中任何地方出现关键词 MUST，MUST NOT，REQUIRED，SHALL， SHALL NOT， SHOULD， SHOULD NOT， RECOMMENDED， MAY，以及OPTIONAL，都将和它们 在[KEYWORDS]中的定义一致。 WWW浏览器‘SHOULD’（应当）在URL中使用本文档定义的IPv6文本格式。其它一些 使用URL的应用和协议‘MAY’（可以）用这种格式。
Literal IPv6 Address Format in URL’s Syntax – URL语法中的IPv6地址文本格式 To use a literal IPv6 address in a URL, the literal address should be enclosed in “[” and “]” characters. For example the following literal IPv6 addresses: 为了在一个URL中使用一文本IPv6地址，文本地址应该用符号“[”和“]”来封闭。 例如下列文本IPv6地址： FEDC:BA98:7654:3210:FEDC:BA98:7654:3210 1080:0:0:0:8:800:200C:4171 3ffe:2a00:100:7031::1 1080::8:800:200C:417A ::192.9.5.5 ::FFFF:129.144.52.38 2010:836B:4179::836B:4179 would be represented as in the following example URLs: 就应该写做下列URL示例： http://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]:80/index.html http://[1080:0:0:0:8:800:200C:417A]/index.html http://[3ffe:2a00:100:7031::1] http://[1080::8:800:200C:417A]/foo http://[::192.9.5.5]/ipng http://[::FFFF:129.144.52.38]:80/index.html http://[2010:836B:4179::836B:4179]
Changes to RFC 2396 —对RFC 2396的修改 This document updates the generic syntax for Uniform Resource Identifiers defined in RFC 2396 [URL]. It defines a syntax for IPv6 addresses and allows the use of “[” and “]” within a URI explicitly for this reserved purpose. 本文档包括了一个对在RFC 2396 [URL]被定义的统一资源标识符中的一般性语法的 更新。为了这个预定目标，本文档明确定义了IPv6地址的语法规则并允许在统一资源 标识符中使用“[”和“]”符号。 Hinden, et al. Standards Track [Page 2] RFC 2732 IPv6 Literal Addresses in URL’s December 1999 The following changes to the syntax in RFC 2396 are made: 对RFC 2396中语法的一些改变如下： (1) change the ’host’ non-terminal to add an IPv6 option: 在‘主机（host）’末端增加一节IPv6项 ： host = hostname | IPv4address | IPv6reference ipv6reference = “[” IPv6address “]” where IPv6address is defined as in RFC2373 [ARCH]. 这里的IPv6地址和RFC2373 [ARCH]中定义的一致。 (2) Replace the definition of ’IPv4address’ with that of RFC 2373, as it correctly defines an IPv4address as consisting of at most three decimal digits per segment. 由于RFC 2373中“IPv4地址”的定义更清晰的说明了IPv4地址是由每节最多三个 十进制数组成的，所以用这个定义来替换RFC 2396中的定义。 (3) Add “[” and “]” to the set of ’reserved’ characters: 在’设定‘符号组中增加“[”和“]”： reserved = “;” | “/” | “?” | “:” | “@” | “&” | “=” | “+” | “$” | “,” | “[” | “]” and remove them from the ’unwise’ set: 并且把它们从’非合理‘符号组中去掉： unwise = “{” | “}” | “|” | “\” | “^” | “‘”
Security Considerations 安全考虑 The use of this approach to represent literal IPv6 addresses in URL’s does not introduce any known new security concerns. 这种在URL中使用文本IPv6地址的表述方法的应用不会引起任何新的已知安全问题。
