C类网络 48 安全考虑 81 作者地址 81 1. 介绍 网络工作组RFC为当前的安排网络号和网关自治系统安排号码作了文档。RFC周期性更新，在任何情况下，最新的信息可以通过DDN网络信息中心（NIC）的机管Hostmaster获得。 Hostmaster DDN Network Information Center SRI International 333 Ravenswood Avenue Menlo Park, California 94025 Phone: 1-800-235-3155 Network mail: HOSTMASTER@NIC.DDN.MIL 基本所有的互联网协议的文档都在RFC的笔记系列里。有一些列出的项目没有文档。更多的关于协议的信息能过在Internet Activites Board (IAB)的出版备忘录，“IAB官方协议标准[52]”里找到，他描述了路联网协议标准的状态。本文档是季刊。当前的拷贝可以通过DDN网络信息中心得到。 下面的列表包括每一个注册的网络或者自治系统的负责人的姓名和网络油箱。括弧内，比如[nn,iii]，在叶面的右手边界，指示了列出网络或者自治系统的引用，其中数字（“nn”）引用了文档同时字母（“iii”）引用了NIC授权负责人。NIC授权是唯一的标示符用于NIC WHOIS/NICNAME服务。个人经常改变电子邮箱。为了找到个人的当前网络油箱或者电话号码，，或者得到关于注册网络的信息，请使用NIC WHOIS/NICNAME服务或者联系 HOSTMASTER@NIC.DDN.MIL。 互联网协议的文档约定是用十进制表示数值，最高的字节在左边同时最低的字节在右边[39]。 文档内描述的消息头和内容的发送顺序详细到字节的级别。无论何时一个图显示一组字节，这些字节的发送顺序是他们在英文中的阅读顺序。例如，在下面的图中字节按照它们的编号发送。 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | 1 | 2 | 3 | 4 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | 5 | 6 | 7 | 8 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | 9 | 10 | 11 | 12 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 字节发送顺序 无论何时表达数字量的一个字节图中的最左位是最高位或者最重要位。也就是说，标记为0的位是最高位。例如，下面的图表达了170这个值（十进制）。 0 1 2 3 4 5 6 7 +-+-+-+-+-+-+-+-+ |1 0 1 0 1 0 1 0| +-+-+-+-+-+-+-+-+ 同样，无论何时表示一个数字量的一个多字节的域认为整个域的最左边的位是最高位。当一个多字节的量在传输的时候最高位先传输。 2. 网络号 这里列出的网络号作为互联网地址被用在互联网协议中(IP) [14,26]。IP协议使用32位的地址域同时把地址分为网络部分和“其余”或者说本地地址部分。区分为四类地址。 第一类地址，或者类A，有7位的网络号码和24位的本地地址。最高位设置为0。可以有128个A网络。 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |0| NETWORK | 本地地址 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Class A 地址 第二类地址，或者类B，有14位网络号和16位本地地址。最高的两位设置为1-0。可以有16，384个B网络。 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1 0| NETWORK | 本地地址 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Class B 地址 第三类地址，或者类C，有21位网络号和8位本地地址。最高的三位设置为1-1-0。可以有2,097,15个C网络。 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1 1 0| NETWORK |本地地址 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Class C 地址 第四类地址，或者类D，用于多播[13]。最高的四位设置为1-1-1-0。 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1 1 1 0| 多播地址 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Class D 地址 注意：不存在最高位是1-1-1-1的地址。这些地址，称为“类E”，是保留的。 一个通用的互联网主机地址表示法是区分32位的地址为4个8位的地址域，每个域的值表示为十进制数并用句号分开。这就是“点分十进制”。例如，VENERA.ISI.EDU的点分十进制地址是128.009.000.032, 或者128.9.0.32。 点分十进制表示法用来表示安排网络号。类A网络是nnn.rrr.rrr.rrr，类B网络是nnn.nnn.rrr.rrr，类C网络是nnn.nnn.nnn.rrr，其中nnn表示了网络号的全部或者部分，rrr表示了本地地址的全部或者部分。 有四类互联网地址用户：研究，国防，政府（非国防），商业。为了反映类中的分配的网络标示符，一个1字母的编码放在网络号的最左边：R表示研究，D表示国防，G表示政府，C表示商业（附录A详细给出网络标示符区分）。 网络号分配给连接在研究互联网，运营互联网，使用IP族协议的独立网络（通常是商业）的网络。这些独立网络在数字前面有个*号。 独立网络的管理者必须单独申请接入互联网的允许。独立网络不应该列入互联网主机或网关的工作表。 由于多种原因，网络安排号码有时改变。为了容易改变旧的号码会在过渡期内同时列出。这些“旧的号码”入口会表示为“T”在数字后面在名字前面，网络名后缀是"-TEMP"。 特别地址: 在某些情况下，特殊意义的固定地址比特殊的主机标示符更有用。 地址0翻译为“这个”，就是说“在这个网络”。 例如，0.0.0.37翻译为本网络的37主机。 地址全1翻译为“所有”，就是说“所有主机”。 例如，地址128.9.255.255翻译为网络128.9的所有主机。 类A网络号127安排为“回环”功能，就是说，高层协议发送到网络地址127D的数据包应该被送回这个主机。在网络上是不能出现发送给网络地址127的数据包的。 3.
