根据部门以及职员人数，比如说192.168.1.2-10给领导层，11-15给财务部，16-30给行政部......以此类推根据相应的部门和人员数，把IP地址分好，分完以后把你的路由器设备的DHCP地址重新配置一下，比如说你吧刚才的IP设置到了100 那么你的DHCP地址池开始IP是101结束IP是254这样来零时上网的就自动获取IP而且也不会存在冲突的可能性。
在网关设备和线材的选择上是关键，以为企业路由器必须要有基本的流控和上网行为管理功能，因为企业中的网络问题主要就是这两方面导致的，1、员工大量下载、在线视频、的一系列的P2P下载行为抢占带宽，导致工作业务无法正常进行；在有就是一些随意的上网行为导致员工电脑中病毒了，这些病毒发起内网攻击导致全网不能正常运行。
我是这么认为路由器不等于安全！！！
而免疫墙路由器重点突出的是免疫墙三个字，免疫墙路由器的诞生直接导致了路由器的灭亡。也就是说一个安全的接入设备才是大家最需要。而欣向的免疫墙路由器，就是融合了安全机制，替代了原有路由器，使网络更加稳定、安全、可靠。所以说啊，使用免疫墙路由器才是我们做网管最明智的选择。
免疫墙技术做的就是直接在网卡上进行拦截和控制。其主要特征：拓展到网络的最末端，深入到协议的最底层、盘查到外网的出入口、总览到内网的最全貌，就是希望通过网络本身对网络病毒全面抵御，同时完善对业务的管理，使网络可控、可管、可防、可观。
公司小就用C类地址，可以一个部门一个网段，VLAN有必要就搞，也可以一个部门一个VALN，网络设备的选购时隔很重要的东西，防火墙其实可有可无，毕竟不是每个公司都需要他，不过内网安全就很必要了，因为你带宽假设4M的光纤那么外网的攻击量也就最多4M了，但是内网的每个节点都可能成为一个攻击源，那他的攻击这个数量就不得了啦。所以建议你把内网安全这块得重视起来，你在选购设备的时候可以去找一下相关资料，因为内网安全涉及很多，桌面安全、系统安全、文件加密、底层安全。这其中最重要的就是底层安全了，因为就跟一栋楼的地基一样，咱得把地基打牢靠的，底层安全的话你得去找下免疫墙。。
