For example, the subnet mask of the Class A address with the partitioning scheme defined above is shown in this figure. The subnet mask is a set of 4 bytes, just like the Internet address. The subnet mask consists of high bits (1's) corresponding to the bit positions of the network an...
Structure of Subnet Masks To split a network identifier, use a subnet mask. A subnet mask distinguishes the network identifier from the host identifier in an IP address, but is not restricted by the same rules as the class-based method. A subnet mask, like an IP address, is made up of...
On each adapter a Loop Back subnet named #LOOP1 is automatically added with an IP Address of 127.0.0.1. This is to provide a method of testing the TCP/IP process. Each SUBNET is associated with a SUBNET MASK depending on the class of the network. View chapter Book 2006, Securing HP No...
For class B address, if its subnet mask is 255.255.252.00, how many useble host are there in each subnet? ( D )a.64b. 256c. 510d. 1022 相关知识点: 试题来源: 解析 d 对于B类地址,默认子网掩码为255.255.0.0(即前16位为网络号)。题目中给定的子网掩码为255.255.252.0,转换为二进制为: ...
Each class is identified by its subnet mask. By the categorization of a default subnet mask, we can easily identify the class of an IP address of the network. The first octet of an IP address identifies the particular class of an IP address. ...
The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or a remote network. With a local subnet, the device will send a request to retrieve the hardware address of the system to communicate over the data-link layer. For addresses on remote net...
The class B IP address subnet mask is 255.255.255.240, so the number of host addresses available in each subnet is( )A. 10B. 8C. 6D. 14 相关知识点: 试题来源: 解析 D B类地址默认子网掩码为255.255.0.0(16位)。此题中子网掩码为255.255.255.240,即二进制前28位为网络/子网部分(11111111 ...
This article (with pictures) explains how to locate an IP Range's subnet mask, gateway, and DNS IP address
Consider the example ofClass C network192.168.10.0 255.255.255.0, we discussed above. If we include one bit from the host part to the network part in the last octet, the defaultsubnet maskofClass C network255.255.255.0 is changed into 255.255.255.128. The single bit that is added to the ...
