all provisions of Section 10 of RFC 2026 [STD-PROC].
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
other groups may also distribute working documents as Internet-
Drafts.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet- Drafts as reference
material or to cite them other than as "work in progress."

Abstract
This document defines the preferred 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.

INTERNET-DRAFT IPv6 Literal Addresses in URL's June 1999
1. Introduction
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 preferred 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.
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.
1.1 Requirements
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].
2. Literal IPv6 Address Format in URL's Syntax
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:
FEDC:BA98:7654:3210:FEDC:BA98:7654:3210
1080:0:0:0:8:800:200C:417A
1080::8:800:200C:417A
::13.1.68.3
::FFFF:129.144.52.38
would be represented as in the following example URLs:
http://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]:80/index.html
http://[1080:0:0:0:8:800:200C:417A]:80/index.html
http://[1080::8:800:200C:417A]:80/index.html
http://[::13.1.68.3]:80/index.html
http://[::FFFF:129.144.52.38]:80/index.html

3. Security Considerations
The use of this approach to represent literal IPv6 addresses in URL's
does not introduce any known new security concerns.
4. IANA considerations
None.
