面向IPv6局部无服务器DNS 名称解析发布时间：2006-09-21 08:00:00 来源： 作者： 点击：196 局部无服务器的域名系统局部无服务器的域名系统（（LSLDNS ）局部无服务器的域名系统（LSLDNS ）也称为多播DNS ，它是Microsoft Windows CE 4.1或更新版本提供的IPv6协议中的一项新增功能。
LSLDNS 在标题为“局部无服务器的DNS （LSLDNS ）查询解析”（draft-ietf-dnsext-mdns-07.txt ）的Internet 草案所有描述。
注意在多播Internet 草案的最新修订版中，该协议的名称已改为链路局部多播名称解析（Linklocal Multicast Name Resolution ，LLMNR ），并且许多实施细节已作了改动。
本文不打算描述LLMNR 。
LSLDNS 提供了一种用于在未包含有效DNS 服务器的专用单子网上解析名称的方法。
Windows TCP/IP 中的IPv4通过使用TCP/IP 之上的NetBIOS（NetBT ）来解决这个问题，其中默认启用NetBT 。
通过NetBT ，查询节点可向本地子网广播地址广播一条NetBIOS Name Query Request （NetBIOS 名称查询请求）消息。
拥有所查询的名称的节点向请求者发回一条单播NetBIOS Name Query Response 消息来解析名称。
由于以下原因，这种方法不适用于IPv6：NetBIOS 未定义用以在IPv6上进行运作。
IPv6中没有广播地址。
LSLDNS 是一种用于专用单子网的简单请求-应答机制，可允许IPv6节点在不具备DNS 名称解析功能的情况下实现名称的相互解析。
多子网应该具有有效的路由器和DNS 服务器。
由于广播不是对IPv6定义的，因而采用多播方式。
LSLDNS 在以下几个方面和DNS 类似：使用完全合格的域名（FQDN ）根据RFC 1035中的定义，它和DNS使用相同的消息和消息结构LSLDNS在以下几个方面有别于DNS：LSLDNS消息发送到TCP和UDP端口5353，而不是发送到TCP和UDP 端口53LSLDNS消息查询发送到多播地址，而不是发送到DNS服务器的单播地址LSLDNS名称缓存独立于DNS名称缓存当DNS服务器处于以下情况时使用LSLDNS：未经配置未对查询返回响应含返回代码的响应（RCODE）被设为0，但无任何应答记录含RCODE的响应被设为3（不存在域名）DNS Name Query Request（DNS名称查询请求）消息的多播地址称为请求的名称多播地址，它是根据以下几个部分进行构造的：前缀：FF02::2:0:0/Array6。

为了更便于使用网络资源，名称系统（如DNS）提供一种方法，可将计算机或服务的用户友好名称映射到与该名称关联的其他信息，如IP 地址。
与计算机在网络上通信所使用的数字地址相比，用户友好名称更便于了解和记忆。
大多数人更愿意使用用户友好名称（例如）来查找网络上的电子邮件服务器或Web 服务器，而不愿意使用IP 地址（如157.60.0.1）。
用户在应用程序中输入用户友好DNS 名称时，DNS 服务会将名称解析为其数字地址。
DNS 服务器有何作用？DNS 服务器为基于TCP/IP 的网络提供名称解析。
这使得客户端计算机的用户能够使用名称（而不是数字IP 地址）来识别远程主机。
客户端计算机会将远程主机的名称发送到DNS 服务器，该服务器以相应的IP 地址进行响应。
然后，客户端计算机可以将消息直接发送到远程主机的IP 地址。
如果DNS 服务器的数据库中没有与远程主机相对应的条目，则可以使用很可能具有该远程主机相关信息的DNS 服务器的地址对客户端进行响应，或者可以亲自查询其他DNS 服务器。
此过程可采用递归方式执行，直到客户端计算机收到IP 地址或已确定查询的名称不属于特定DNS 命名空间中的主机为止。
Windows Server® 2008 中的DNS 服务器符合用于定义和标准化DNS 协议的征求意见文档(RFC) 集。
由于DNS 服务器服务符合RFC，并且它可以使用标准的DNS 数据文件和资源记录格式，因此它可以成功地与大多数其他DNS 服务器实现（如使用Berkeley Internet 名称域(BIND) 软件的DNS 实现）一起工作。
此外，Windows Server 2008 中的DNS 服务器还在基于Windows(R) 的网络中具有以下特殊优势：•支持 Active Directory(R) 域服务 (AD DS)DNS 是支持 AD DS 的必要条件。

llmnr协议本文旨在介绍LLMNR协议，其中介绍了LLMNR协议的主要特点、工作原理和典型应用场景。
LLMNR（Link-Local Multicast Name Resolution）协议是一种新型的域名解析协议，它允许使用相同的限定名称解析在多种设备上建立的组播名称。
最初，LLMNR协议作为Windows Vista的一部分推出，它允许两个支持这一协议的客户端在局域网内通过组播方式解析限定名称。
LLMNR协议支持IPv4和IPv6，也支持32位和64位的Windows操作系统。
LLMNR协议的主要特点是能够灵活地解析局域网中的主机名称。
它使用224.0.0.252组播地址以及UDP协议，这意味着客户端之间可以进行通信，而没有必要在每个网络节点之间建立传统的服务器/客户端模型。
另外，它是一种轻量级的协议，所以传输的速度也非常快，并且可以减少潜在的网络拥塞问题。
LLMNR协议的工作原理非常简单，当客户端发起查询时，它会将信息发送给LLMNR域控制器，该控制器会在网络中查找匹配的主机名称，如果找到，则将对应的IP地址发回给客户端。
典型的应用场景有：在局域网环境中，如果在设置DNS服务器或通过它查找计算机的IP地址遇到问题时，可以使用LLMNR协议来进行域名解析；企业网络中，LLMNR协议可以用于跨网段的内部服务查询；在家庭网络中，LLMNR协议可以用于访问内部设备，比如无线打印机。
此外，LLMNR协议还有一些缺点。
首先，由于它是一种基于UDP的协议，因此它更容易受到恶意攻击，比如DNS欺骗等；其次，它只能在IPv4环境下工作，如果要在IPv6环境中使用，则必须使用另一种协议；最后，LLMNR协议可能无法在大网络环境中正常工作，比如跨网段环境。
总之，LLMNR协议是一种新型的域名解析协议，它使客户端之间可以灵活地进行通信，具有良好的传输速度、轻量级的协议等优点。
但是，需要注意的是，LLMNR协议也存在一定的缺点，我们需要注意，以免被恶意攻击等。
第20章TCP/IP网络TCP/IP是由传输控制协议(TCP)和Internet协议(IP)组合成的协议套件，TCP是一种以传输为目的的协议，主要用于可靠的端到端通信；IP是一种网络互联协议，主要用于将称为数据报的数据封包通过网络进行路由。
每个IP数据报都包含报头和载体，报头中包含了用于路由该数据报的信息，例如来源和目标IP地址，载体则包含了实际需要通过网络发送的数据。
TCP/IP是Windows网络的骨干，所有网络互联通信以及到Internet的访问都需要该协议。
在实施TCP/IP网络之前，必须熟悉IP地址约定、子网选项和名称解析技术，这些便是本章的主要内容。
20.1 在Windows Server 2008中浏览网络Windows Server 2008中的网络功能和老版本Windows有很大不同，Windows Server 2008中提供了一套新的网络工具，具体如下。
●网络浏览器为浏览网络上的计算机和设备提供的一个集中的控制台界面。
●网络和共享中心为查看和管理计算机的网络和共享配置提供的集中的控制台。
●网络映射图为描述计算机和设备的连接情况提供的可视化网络拓扑图。
●网络诊断提供的用于诊断和解决网络问题的自动化诊断工具。
在讨论这些网络工具的使用方法之前，必须首先了解这些工具所依赖的Windows Server 2008的新功能，具体如下。
●网络发现Windows Server 2008中的功能，用于控制查看其他计算机和设备的能力。
●网络感知Windows Server 2008中的功能，用于报告有关网络连接和配置的变化信息。
计算机的网络发现设置决定了可以在Windows Server 2008的网络工具中看到的计算机和设备。
网络发现设置会和计算机的Windows防火墙配合工作，以便允许或拒绝：●发现网络上的计算机和设备。
●被网络上的其他计算机发现。
网络发现设置的主要目的是为了给计算机可以连接的不同网络提供级别的安全设置。
在这方面，主要定义了以下三个不同的网络类别。
●域网络专指计算机加入的本机所在的企业域网络。
默认情况下，在域网络上会启用发现功能，这样可以降低对域网络上的计算机发现其他网络计算机和设备的限制。
●专用网络专指被配置为工作组成员的计算机所连接的网络，或者没有直接连接到Internet的网络。
默认情况下，在专用网络上会启用发现功能，这样可以降低对专用网络上的计算机发现其他网络计算机和设备的限制。
●公用网络专指处于公共场所的非内部网络，例如咖啡馆或机场的网络。
默认情况下，在公用网络上会禁用发现功能，这样可以通过防止公用网络上的计算机发现其他网络计算机或设备而增强安全性。
因为计算机可为每种类别的网络分别保存设置，因此每个网络类别都可应用不同的允许或拒绝设置。
当第一次连接到一个网络时，系统会显示一个对话框让我们指定网络的类型为专用或者公用。
如果选择专用，而计算机检测到已经连接到了自己加入的域所在的网络，那么网络类型就会被设置为域网络。
取决于网络类别，Windows Server 2008会自动配置设置以启用或禁用发现功能。
启用(打开)状态意味着以下两点。
●计算机可以发现网络上的其他计算机和设备。
●网络上的其他计算机可以发现本机。
关闭(禁用)状态意味着以下两点。
●计算机无法发现网络上的其他计算机和设备。
●网络上的其他计算机无法发现本机。
图20-1所示的网络浏览器显示了在网络上发现的计算机和设备列表。
单击“开始”，然后单击“网络”即可打开网络浏览器，而在网络浏览器中列出的计算机和设备则取决于本机的网络发现设置。
如果发现功能被禁用，那么将看到有关该情况的通知。
如果单击这条警告信息，然后选择“打开网络发现”，就可以启用网络发现。
这个操作可以打开Windows 防火墙中的端口，从而启用网络发现功能。
如果除了网络发现不再修改其他设置，那么计算机将处于“仅发现”状态，还需要手工设置打印机、文件以及媒体文件的共享。
这些信息请参考第17章。
图20-1 使用网络浏览器浏览网络资源图20-2所示的“网络和共享中心”则提供了当前的网络状态信息和当前网络配置信息的摘要。
可以单击“开始”，然后单击“网络”，并单击网络浏览器窗口工具栏上的“网络和共享中心”按钮打开网络和共享中心程序。
图20-2 通过网络和共享中心查看与管理网络设置“网络和共享中心”窗口中包括以下三个主要部分。
●网络映射摘要图对网络的配置和连接信息提供可视化的描述。
正常状态下，不同的网络设备之间会用线条连接在一起，如果网络的配置或连接存在问题，那么对应的位置就会用代表相应警告的记号标示出来。
如果在配置上可能存在问题，那么会显示黄色的警告图标；如果到特定网络设备的连接出现故障，那么会显示红色的叉。
单击“查看完整映射”链接可以打开完整的网络映射图，其中包含更详细的网络视图信息。
●网络详细信息列出当前网络的名称，并提供网络的信息概览。
网络名称后面括号中的内容代表当前网络的网络类型，可用的值包括“域网络”、“专用网络”和“公用网络”。
“访问”一栏显示当前网络的连接情况，例如是否只连接到本地、只连接到Internet，还是可以连接到本地和Internet。
“连接”一栏显示被用于连接到当前网络的本地网络连接的名称。
如果单击“自定义”链接，还可以更改网络名称、网络类别(仅适用于公用或专用网络)和网络图标。
如果单击“查看状态”链接，则可以在本地网络连接状态对话框中看到当前的连接状态。
●共享和发现提供用于配置计算机的共享和发现设置功能的选项，并列出每类选项当前的状态。
要管理这些选项，可以单击对应选项右侧的展开按钮(显示为向下的箭头)打开选项的视图窗格，单击选中希望使用的设置，然后单击“应用”按钮。
例如，要打开或关闭网络发现，可以展开“网络发现”节点，按照需要选择“启用网络发现”或“关闭网络发现”选项，然后单击“应用”按钮。
在网络和共享中心，我们还可以尝试诊断警告状态。
为此，请单击出现的警告图标，启动Windows网络诊断工具。
随后，Windows网络诊断工具会尝试是否有网络问题并提供相应的解决方案。
注意在网络和共享中心中，可以单击左侧“任务”列表下的“诊断和修复”链接手工进行诊断。
20.2 使用TCP/IP通过TCP和IP协议，计算机便可使用网络适配器，例如网卡、USB接口的网卡、PC Card网卡以及主板集成网卡，通过不同网络甚至Internet进行通信。
Windows Server 2008包含了双重IP层架构，可以同时为Internet协议版本4(IPv4)和Internet协议版本6(IPv6)提供支持，并可以共用通用的传输和框架层。
IPv4和IPv6在使用上有很多不同的方式。
IPv4使用32位地址，并且目前还是大部分网络，包括Internet使用的主要协议。
IPv6使用128位地址，是下一代IP协议。
如果在操作系统的安装过程中检测到网络硬件，那么在Windows Server 2008和Windows Vista中，都会默认启用IPv4和IPv6功能，我们不需要安装额外的组件来启用对IPv6的支持。
这种改进的IP架构被称作下一代TCP/IP协议栈。
表20-1总结了在下一代TCP/IP协议栈中提供的最主要的改进，表20-2则总结了专门用于IPv6的重要TCP/IP改进。
表20-1 下一代TCP/IP协议栈中TCP/IP的重要改进支持的功能描述黑洞路由器自动检测防止TCP连接因为中间路由器暗自丢弃过大的TCP数据包而导致终止、重传或错误信息失效网关自动重试确保定期检查失效网关，以判断该网关什么时候可用复合TCP 通过增大一个连接中发送的数据量，但确保不影响其他TCP连接的方式为发送端优化TCP传输扩展的选择性应答扩展了选择性应答(SACK)的使用方式，使得接收端可以指明接收最多四个非邻接块，并可以接收数据包的副本。
这样可以让接收端判断什么时候重传了不需要的内容，并调整自己的行为以防止更多的重传改善的快速恢复机制如果一个窗口中的多个数据包都丢失了，而发送端收到的回应表示只有一部分数据包被成功接收，则通过改变发送端增加发送率的方式提供更高吞吐率IPv4的邻居不可达检测判断临近的节点和路由器何时不可达，并报告这一情况支持的功能描述网络诊断框架提供可扩展的框架，帮助用户从网络连接故障中恢复或解决连接问题接收窗口自动调节根据当前网络情况，通过自动管理用于存储传入数据的内存缓冲(接收窗口)的大小，为接收端优化TCP传输路由隔间将拥有路由表的登录会话与一个或一组接口进行组合，以防止接口之间产生不必要的转发通信基于SACK的丢失恢复收到重复的通告时可以用SACK信息进行丢失恢复，同时使目标在没有收到多个数据段时更快恢复伪重传超时检测为突发、临时性的重发超时增加提供纠正，并防止不必要的数据段重传TCP扩展状态帮助判断连接的性能瓶颈是位于发送程序、接收程序，还是网络上Windows 筛选平台为扩展的TCP/IP 筛选架构提供应用程序编程接口(API)，以便支持更多功能表20-2 用于IPv6的TCP/IP重要改进支持的功能描述DHCP客户端的DHCPv6支持扩展了DHCP客户端以支持IPv6，并让DHCPv6服务器可以实现状态地址自动配置功能IP安全旨在可以针对IPv6使用Internet密钥交换(IKE)和数据加密PPP协议上的IPv6(PPPv6) 旨在可以通过基于PPP的连接发送原生IPv6通信，这样可以让远程访问客户端通过基于IPv6的Internet服务提供商(ISP)的拨号或PPP over Ethernet(PPPoE)连接创建连接链路局部多播名称解析(LLMNR)旨在使同一子网上的IPv6主机可以不用DNS服务器就接续相互的名称多播侦听发现版本2(MLDv2) 为特定源的多播通信提供支持，类似于针对IPv4的Internet组管理协议第三版(IGMPv3)随机接口ID 防止根据网络适配器制造商的已知公司ID 进行IPv6 地址扫描。
默认情况下，Windows Vista会为自动配置的非临时IPv6地址(例如公共或链路本地地址)生成随机接口ID。
对称网络地址转换取决于外部目标地址，将内部(专用)网络的地址和端口号映射为不同的外部(公用)地址和端口20.3 理解IPv4寻址IPv4带给我们最重要的资产就是IPv4地址，正是因为有了IPv4地址的存在，信息才能通过网络从A点路由到B点。
IPv4地址是32位的逻辑地址，包含两个组件：网络地址和节点地址。
通常来说，IPv4地址可以分为四个称为“octet”的8位值，书写的时候则可以写成四段由小数点(读作“Dot”)分隔的十进制数值。
二进制数值可以通过添加用数字“1”代表的表示位数的数字的方法转换为十进制等价值，通常我们可以把这样的值写成“w.x.y.z”的形式，其中每个字母都代表四个octet之一。
