基于IPV6DNS应用探讨 　　摘要：随着互联网在社会生活各个领域的广泛应用和商业化的深入发展，现有的网络基础设施和网络服务已经难以满足和支持大规模的网络应用，如交互式远程实时教学、协同科研、数字化图书馆、虚拟实验室等。与此同时，随着网络规模的扩大，现有网络的管理和运营已经变得非常复杂，地址空间匮乏、带宽瓶颈、网络安全、数据必威体育官网网址、服务质量等问题变得越来越突出。本文通过对IPV6的特点、协议体系等核心技术的分析，结合在实际工作中的一些具体应用，针对IPV4下地址空间严重不足等实际问题，讨论了使用双栈和隧道技术的路由器产品使用的可行性及基于双栈技术的网络迁移方案和基于隧道技术的网络迁移方案，提出了基于IPV6的一些切实可行的解决方案，并对它的实现进行了一些积极的探讨。 　　关键词：IPV6；协议体系；双栈；隧道技术；DNS分配；应用；分析；实现 　　中图分类号：TP393文献标识码：A文章编号：1009-3044(2007)17-31572-04 　　Based on IPV6 DNS Application Discussion 　　HUANG Hui-hong 　　(Shanghai No.2 Light Industry School, Shanghai 200135, China) 　　Abstract:Along with the Internet in the social life each domain widespreadapplication and commercialization the thorough development, the existingnetwork infrastructure and the network service already with difficultysatisfied and supports the large-scale network application, likeinteractive long-distance real-time teaching, coordination scientificresearch, digitized library, hypothesized laboratory and so on. At thesame time, along with the network scale expansion, the existingnetwork management and the operation already changed extremelycomplex, the address space was deficient, question and so on bandwidth bottleneck, network security, data security, grade of servicechanges more and more prominently. This article through to coretechnology the and so on IPV6 characteristic, agreement systemanalysis, unifies in the practical work some concrete applications, inview of IPV4 under actual problem and so on address space seriousinsufficiency, discussed has used the double stack and the tunneltechnology router product use feasibility and based on the doublestack technology network migration plan and based on the tunneltechnology network migration plan, proposed based on the IPV6 somepractical feasible solutions, and has carried on some positivediscussions to its realization. 　　Key words:Agreement system; Double stack; Tunnel technology; DNS distribution; Application; Analysis; Realization 　　 　　1 引言 　　 　　IPV6技术体系经历了多年
