IP地址与子网掩码(IP address and subnet mask) IP address and subnet mask 1, IP address: Internet networks are interconnected by different physical networks, and computer communications between different networks must have corresponding address identification, which is called the IP address. IP addresses...
In a normal home network, the Subnet Mask is usually “255.255.255.0”. What that means is that the three first parts of the IP address determine which IP network that the IP addresses belong to. The last part of the IP address determines which unique address within that IP network that ...

Each of the address classes has a different default subnet mask. You can identify the class of an IP address by looking at its first octet. Following are the ranges of Class A, B, and C IP addresses, each with an example address: Class A networks use a default subnet mask of 255.0....
This example assumes that the following details have been configured in the IP Address filter: FieldValue IP Address 192.168.0.36 Net Mask 255.255.255.255 Step 1: AND the IP address and Netmask configured in the IP Address Filter: 11000000.10100000.00000000.00100100 (192.168.0.36) AND ...
If the subnet mask is 255.255.0.0, then the first two octets of all devices must be the same. The combination of the last two octets must be different and unique. 65,534 devices can be used in this subnet. The very first address and very last address in a subnet are specially reserved...
For Example, take a pair of IP address and subnet mask 10.20.12.2 255.0.0.0 #1)Convert this Combination into a binary value: #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. ...
This example assumes that the following details have been configured in the IP Address filter: FieldValue IP Address 192.168.0.36 Net Mask 255.255.255.255 Step 1: AND the IP address and Netmask configured in the IP Address Filter: 11000000.10100000.00000000.00100100 (192.168.0.36) AND ...
Example 1:IP address: 10.0.0.55 and Subnet Mask:255.255.255.0 Therefore: Subnet ID: 10.0.0.0 and Host ID:55 Example 2:IP address: 172.16.14.101 and Subnet Mask:255.255.248.0 Therefore: Subnet ID: 172.16.8.0 and Host ID:14.101 Similarly to the previous example, we perform a bitwise AND op...
Address: Subnet: Subnet mask: A 32-bit combination used to describe which portion of an adress refers to the subnet and which part refers to the host. Interface: A network connection Net ID: Host ID: Subnetwork ID: 2. IP Address: ...
