DOD INTERNET HOST TABLE SPECIFICATION

STATUS OF THIS MEMO

   This RFC is the official specification of the format of the Internet
   Host Table. This edition of the specification includes minor
   revisions to RFC-810 which brings it up to date. Distribution of this
   memo is unlimited.

INTRODUCTION

   The DoD Host Table is utilized by the DoD Hostname Server maintained
   by the DDN Network Information Center (NIC) on behalf of the Defense
   Communications Agency (DCA) [See RFC-953].

LOCATION OF THE STANDARD DOD ONLINE HOST TABLE

   A machine-translatable ASCII text version of the DoD Host Table is
   online in the file NETINFO:HOSTS.TXT on the SRI-NIC host. It can be
   obtained via FTP from your local host by connecting to host
   SRI-NIC.ARPA (26.0.0.73 or 10.0.0.51), logging in as user =
   ANONYMOUS, password = GUEST, and retrieving the file
   "NETINFO:HOSTS.TXT". The same table may also be obtained via the NIC
   Hostname Server, as described in RFC-953. The latter method is
   faster and easier, but requires a user program to make the necessary
   connection to the Name Server.

ASSUMPTIONS

   1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
   sign (-), and period (.). Note that periods are only allowed when
   they serve to delimit components of "domain style names". (See
   RFC-921, "Domain Name System Implementation Schedule", for
   background). No blank or space characters are permitted as part of a
   name. No distinction is made between upper and lower case. The first
   character must be an alpha character. The last character must not be
   a minus sign or period. A host which serves as a GATEWAY should have
   "-GATEWAY" or "-GW" as part of its name. Hosts which do not serve as
   Internet gateways should not use "-GATEWAY" and "-GW" as part of
   their names. A host which is a TAC should have "-TAC" as the last
   part of its host name, if it is a DoD host. Single character names
   or nicknames are not allowed.

--------------

无论您何时使用百分号、井号或下划线的计算机名称中 Windows NT 初始安装期间替换连字符（减号）。例如，%myname、 MYNAME #1，和分别变成 MYNAME_1、-MYNAME MYNAME-1、和 MYNAME 1。
不能添加百分号、井字号或为 DNS 主机名的下划线，即使服务器安装指南中不会列出他们为无效字符。
如果您尝试插入字符无效，会显示以下错误：

参数不正确。

当您尝试连接到新创建的 Web 服务器上，与在计算机名称中无效的字符时，会出现其他症状。您不能连接到 HTTP://SERVER#1，但您可以连接到 HTTP://SERVER-1。

原因

RFC 952，规定给出了此错误消息的原因：

在"名称"（网络、主机、网关，或域的名称）是最多为 24 个字符从字母 (A-Z)、数字 (0-9)、减号 (-) 和句点 (.) 绘制文本字符串。请注意，当它们用于分隔"域的样式名"的组件时只允许使用英文句号。（请参阅 RFC-921，"域名称系统实施计划"，背景）。不为空或允许它们空格字符作为名称的一部分。不区分大小写之间。第一个字符必须是字母字符。最后一个字符不得减号或期限。充当网关应具有的主机"的网关"-网关"作为其名称的一部分。不执行它是作为 Internet 网关不能使用主机"的网关"和"-网关"作为它们的名称的一部分。这是一个 TAC 主机应该有"-TAC"如果是 DoD 主机的主机名的最后一次的一部分。不允许单个字符的名称或昵称。

DOD INTERNET 主机表规范： -------------------------------------- 此 rfc 文档是 Internet 的格式的正式规范主机列表。规范的此版本包括 RFC-810 它提供了其最新的次要修订。此备注的分布是无限制。

通过设计，在 Microsoft Windows NT DNS 主机配置实用程序替换连字符在 NetBIOS 计算机名称中找到 DNS 主机名中的所有无效字符。您是否以匹配您 NetBIOS 和 DNS 主机名必须使用创建您的 NetBIOS 计算机名称时所述 RFC 952 DNS 命名标准。

替代方法

在控件面板网络中 TCP/IP 协议的 DNS 配置对话框中，为有效的字符串的字符更改主机名。欲 RFC 文档的详细信息，请参阅： http://www.rfc-editor.org/
