in an IP address, how many bits are used in the network address and how many bits are left for the host address is determined by the subnet mask. The subnet mask is also 32 bits in length and uses the same notation
#2)The bits corresponding to the subnet mask with all 1’s represent the network ID as it is a class A network and the first octet represents the network ID. The bits corresponding to all 0’s of the subnet mask is the host ID. Thus the network ID is 10 and the host ID is 20.12...
If the Subnet Mask is 255 in the first part then the first part of the IP address shows what IP network the address belongs to. If the second part of the Subnet Mask is also 255, then the second part of the IP address is also part of the IP network. If the third part of the S...
IPv4引入了子网掩码（subnet mask）的概念，它是一个32位二进制数，其中与网络号对应的位为1，与主机...
The time and space complexities of finding the range of IP addresses are because we just need to put the subnet mask in a formula to find the range. 9. Conclusion In this article, we have explained a simple method to estimate the range of possible IP addresses from the subnet mask.2...
Figure 5-1: Network settings – Scanner PLC Important settings are the IP address and the subnet mask. As shown above the are: • IP: 192.168.74.12 • Mask: 255.255.255.0 Compatible IP addresses differ on a network with subnet mask 255.255.255.0 only in the last octet. Otherwise, a ...
Subnet masks A single IP address identifies both a network, and a unique interface on that network. A subnet mask can also be written in dotted decimal notation and determines where the network part of an IP address ends, and the host portion of the address begins. ...
ClassDandEare not used for the host addressing. Class D addresses are used for multicast addresses. Class E addresses are reserved for research and development purposes. Multicast addresses are explained in the following tutorial. The subnet mask ...

If you plan to subnet a class-based IPv4 network, you need to define a subnet mask, or netmask, as explained in netmasks Database.The next example shows of the CIDR format address 192.168.3.56/22 Figure 2–2 CIDR Format IPv4 Address...
