解释System.Net.IPAddress的实例属性 [英] Explain the instance properties of System.Net.IPAddress

问题描述

我有一个小麻烦了解 System.Net.IPAddress 类，因为我不知道去哪里找什么的一些属性是指的定义。具体来说，什么是：

I'm having a little trouble understanding the System.Net.IPAddress class, because I don't know where to look for a definition of what some of the properties are referring to. Specifically, what are:

 IPAddress.IsIPv6LinkLocal
 IPAddress.IsIPv6Multicast
 IPAddress.IsIPv6SiteLocal
 IPAddress.IsIPv6Teredo

我会很乐意接受指向解释这些概念的资源答案。 MSDN网站已证明是不够的。

I will also happily accept an answer that points to a resource that explains these concepts. The MSDN site has proved insufficient.

推荐答案

的 IPAddress.IsIPv6LinkLocal

一个链路本地地址是IP地址
是只打算本地
子网中
通信。路由器做链路本地地址不转发
包

A link-local address is an IP address that is intended only for communications within the local subnetwork. Routers do not forward packets with link-local addresses.

的 IPAddress.IsIPv6Multicast

一个组播地址是一个逻辑
标识符组中的
计算机网络主机，可用
来处理数据报或帧
意为组播为
指定的网络服务。组播
寻址所用的链接
层（第2层在OSI模型），例如
作为以太网多播中使用，并在
。互联网层（第3层为OSI）的为
Internet协议版本4（IPv4）或
版本6（IPv6）组播。

A multicast address is a logical identifier for a group of hosts in a computer network, that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the Link Layer (Layer 2 in the OSI model), such as Ethernet multicast, and at the Internet Layer (Layer 3 for OSI) for Internet Protocol Version 4 (IPv4) or Version 6 (IPv6) multicast.

的 IPAddress.IsIPv6SiteLocal

一个独特的本地地址（ULA）是在块FC00 :: / 7，
在RFC 4193.限定的
IPv6地址这是IPv4专用
地址的IPv6
对应。唯一的本地地址都在专用网络中，
例如使用
内的单个位点或
的组织，或跨越网站或组织的有限
号码。它们
是没有在全局IPv6
因特网可路由

A unique local address (ULA) is an IPv6 address in the block fc00::/7, defined in RFC 4193. It is the IPv6 counterpart of the IPv4 private address. Unique local addresses are available for use in private networks, e.g. inside a single site or organisation, or spanning a limited number of sites or organisations. They are not routable in the global IPv6 Internet.

IPAddress.IsIPv6Teredo

在计算机网络中，Teredo是一个
过渡技术，给出了支持IPv6的
主机这是在IPv4 Internet上的
但没有直接的本地
连接到IPv6网络全
IPv6连接。
相比其它类似的协议
其显着特点是，它
为能够从后面的网络地址
转换（NAT）设备，诸如家用执行其功能甚至

路由器。

In computer networking, Teredo is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts which are on the IPv4 Internet but which have no direct native connection to an IPv6 network. Compared to other similar protocols its distinguishing feature is that it is able to perform its function even from behind network address translation (NAT) devices such as home routers.
