摘要
根据TCP/IP协议的通信原理,在TCP/IP网络中的每一台计算机都必须要有一个合法的IP地址,这样才能进行正常的通信。而目前IPv4中所有可用的IP地址已面临耗尽,很多电信部门提供给一个客户的最大IP地址数只有16个,这对于一些稍大型的企业(比如校园网)来说,是远远不够用的。基于此,可采用3种通信方法,即NAT。
According to TCP/IP agreement, each computer in TCP/IP network must have a legal IT address to communicate regularly. Now all the Itaddresses available are using up. Telecommunication departments can provide sixteen IP addresses at the most for a user. It抯 far from enough for from enough for a enterprise such as campus network. We can ease the shorrage of Ipv4-IP address with the communication methods such as NAT, NAT and Proxy Server.
