论文题目：宿舍网络安全探究 专 业：电子信息技术工程 准考证号： 学生姓名：宫野 指导教师：秦贵和 2012 年 3月 7 日 宿舍网络安全探究 摘 要 Internet是一个开放的、互操作的系统，其基础协议是TCP/IP。nternet协议地址（简IP地址）是TCP/IP中可寻址设施的唯一逻辑标识，它是一个32位的二进制无符号数。对于Internet上的任一主机，它都必须有一个唯一的IP地址。IP地址由InterNIC及其下级授权机构分IP地址的主机不能够直接连接到Internet。Internet的迅速发展，IP地址的消耗非常快，据权威机构预测，现行IPv4版本的IP只够2007年。现在，企业、机构、个人要申请到足够的IP地址都非常困难，作为一种稀缺资IP地址的盗用就成为很常见的问题。特别是在按IP流量计费的CERNET网络，由于费用是IP地址进行统计的，许多用户为了逃避网络计费，用IP地址盗用的办法，将网络流量计费IP地址盗用的方式来逃避IP地址盗用侵害了Internet网络的正常用户的权利，并且给网络计费、网络和网络运行带来了巨大的负面影响，因此解决IP地址盗用问题成为当前一个迫切的课题。IP地址的盗用方法多种多样，其常用方法有种静态修改IP地址成对修改IP-MAC地址IP盗用问题，IP地址的盗用。 通信系统 IP地址盗用 Dormitory network security explored Pick to Internet is an open, interoperable communications system, its basic agreement is TCP/IP. Internet protocol address (hereinafter referred to as the IP address) is TCP/IP network addressable facilities of the only logical logo, it is a 32-bit binary unsigned number. For the Internet of any one of the host, it must have a unique IP address. IP address and its authorized organization by InterNIC at a lower level distribution, not assigned to own the IP address of host cant directly connected to the Internet. With the rapid development of Internet, the consumption of IP address is very fast, according to authorities forecast, the current IPv4 version of the IP only enough to 2007. Now, enterprises, institutions and individuals who want to apply for to enough IP address is very difficult, as a scarce resource, the IP address for theft will become very common problem. Especially in the IP flow of billing CERNET network, because of cost is according to the IP address of the statistics, many users in order to escape network billing, with IP address to the theft, network flow billing passed on to others. In addition, some users because some ulterior purpose, USES the IP address of the theft way to avoid tracking, to hide their identity. IP address infringement of Internet network theft of normal user rights, a
