在网络的配置中,必须建立一个由主机和路由器使用的子网掩码(Subnet mask)。本质上,子网掩码是一个32位的模板,与IP地址进行一个逻辑与(AND)运算就可以迅速得到一个路由决定。对应于网络号部分,掩码中的值为1,而对应于主机号部分,掩码中的值为0 相关知识点: 试题来源: 解析 用于确定IP地址中的网络部分和主机部...
Mask 255.255.255.0 has 16 bits for the subnet and 8 bits of the host. Have possible 28-2 hosts =254 which is enough. 2. – You have been allocated a class B network address of 135.1.0.0 and and need to create 4 subnets each with around 200 hosts what is the easiest mask to use ...
1>子网掩码(subnet mask)又叫网络掩码、地址掩码、子网络遮罩,它是一种用来指明一个___的哪些位标识的是主机所在的子网以及哪些位标识的是主机的位掩码。子网掩码不能单独存在,它必须结合IP地址一起使用。子网掩码只有一个作用,就是将某个IP地址划分成网络地址和主机地址两部分。 2>利用子网数来计算 ,利用主机...
Note:Subnet mask is most widely used everywhere in a computer networking system. Hence, there is one more method to represent the subnet mask of a particular network which is chosen and standardized as it is easy to denote and memorize. Subnet mask– 255.255.255.248 (binary) 11111111.11111111.1...
But how can you tell if two IP addresses belong to same IP network? Unfortunately, it isn’t as easy to tell IP networks apart from one another as it is with street addresses. The answer is within something called aSubnet Mask. The Subnet Mask determines how much of the IP address that...
Subnet Mask的缩写形式,即可变长子网掩码。 B. 是指使用不同于整个字节的子网掩码划分方法,使用按位划分网络位和主机位的子网划分方法。 C. 如果仅仅使用非整字节的子网掩码位数,并不能称之为VLSM D. 如果一个企业使用了一个C类的网络进行了整体的规划,并且划分了至少6个不同大小的网络,则可以肯定这个企业内...
The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted. The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C netwo...
子网掩码[1](subnet mask)的目的是让机器从IP地址迅速算出主机地址;由一连串1和接着的一连串0组成,而0的个数就是网络前缀的长度。A,对B,错
