通过此菜单新建的网段都会被分配在“IPMaster-Root”节点下,成为IP地址库的根,其节点类型默认为“可再分”,如果想对此网段做进一步的子网划分,可在此网段节点上单击右键,在弹出的右键菜单中选择“Divide Subnet(划分)”菜单项,即可对网段进行划分。 2.3 子网自动划分功能 在可再分类型的节点上,单击右键,在弹出的...

划分子网时,要保证充分利用地址资源,使子网的划分满足主机个数的要求。 利用可变长子网掩码VLSM(Variable Length Subnet Mask)技术分配IP地址,充分合理地利用地址资源。 与网络的路由机制设计相结合,合理使用已划分的地址空间,提高地址的利用率。 层次性 连续性 扩展性 高效性...
终于到了今天的主角 CIDR,全称为 Classless Inter-Domain Routing,名字有些绕口,这不重要,第一个单词 classless 就表明了,CIDR 是与上面提到的,以分类(class)来切割 IP 地址的方式所对应的新方式。CIDR 是新的子网掩码的表达方式和路由方式。这里注意 CIDR 和 CIDR notation 的区别,CIDR notation 是描述 IP 地址...

There is an important point to be noticed that the more the bits we carry from the subnet mask for host ID then the more will be the subnets obtainable for the network. Example 2: Class B Network: Subnet mask Notation in binary
IP Addressing tutorial explaining how subnet masks work, the variable length subnet mask, RFC1918, Class C and Class D addresses, the wildcard mask, the broadcast address and the private address.
