根据现有 IPv4 地址的部署速度,剩余的地址将在 10 到 20 年被使用殆尽.因此网络逐渐从 IPv4 向 IPv6 转换是不可避免的,相应的各种网络应用程序都将支持 IPv6.对于 Java,从其 1.4 版开始对 IPv6 提供了较好的支持,对程序员基本屏蔽了 IPv4 和 IPv6 的差异,但其中仍有一些 IPv6 引起的变化需要我们小心处理.针对这一情况,本文介绍了如何运用现有的 Java 技术应对这些变化. IPv6 背景介绍 目前我们使用的是第二代互联网 IPv4 技术,它的最大…

IPv6的一些特殊地址   2008年7月3日第二次修正! 昨天是修正了地址部分,本想发上来的,没来得及.今天修正了NDP协议,接下来会是路由和转换部分. 总结一下各协议的精华:OSPF在于LSA,BGP在属性和策略,IPV6在地址和NDP协议,组播的精华在哪呢?嗯,想起来了,在PIM SM模式中源树的共享树的形成和收敛过程.有时候想想,或许我该去考考IE 第一次总结: 颠覆,又是一个颠覆!否定之否定! 大致的过了一遍,不懂的甚多,诸如被请求节点多播地址什么时候用,怎么个用法等,还得继续深入! …
IPv6地址介绍 2008 年 04 月 10 日 1. 认识IPv6地址 IPv4地址是类似 A.B.C.D 的格式,它是32位,用\".\"分成四段,用10进制表示:而IPv6地址类似X:X:X:X:X:X:X:X的格式,它是128位的,用\":\"分 成8段,用16进制表示:可见,IPv6地址空间相对于IPv4地址有了极大的扩充. RFC2373 中详细定义了IPv6地址,按照定义,一个完整的IPv6地址的表示法:xxxx:xxxx:xxxx:xxxx:xxx…

·IPv4的局限性:   1.地址空间的局限性:IP地址空间的危机由来已久,并正是升级到IPv6的主要动力.   2.安全性:IPv4在网络层没有安全性可言,安全性一直被认为是由网络层以上的层负责.   3.自动配置:对于IPv4节点的配置比较复杂,让很多普通用户无所适从.   4.NAT:破坏了Internet端到端的网络模型.   5.由于IPv4地址分配杂乱无章,没有层次性,网络设备需要维护庞大的路由表项.   6.IPv4包头过于复杂,使得网络节点处理的效率不高.   IPV6的好处:…
