default subnet mask A subnet mask that is used on an Internet Protocol version 4 (IPv4) class-based network. The subnet mask for Class A is 255.0.0.0. The subnet mask for Class B is 255.255.0.0. The subnet mask for Class C is 255.255.255.0....
The Class C subnet mask tells you the first 24 bits of the IP address represent the network portion of the address. The remaining 8 bits represent the host address within the network. If a host has the IP address 192.168.2.3, the network portion of the address would be 192.168.2.0. The...

The default subnet mask for each class is: Class A: 255.0.0.0 Class B: 255.255.0.0 Class C: 255.255.255.0 Classless Subnetting (VLSM) Classless subnetting (VLSM) is a method of subnetting that allows for more flexibility in subnet design. VLSM does not use the three classes of IP address...
Default Subnet mask:255.255.255.0 (in decimal) Default Subnet mask:11111111.11111111.11111111.00000000 (in binary) Thus the number of bits are 8+8+8+0= 24 bits. As mentioned earlier, for subnetting in class C network, we will borrow bits from the host portion of the subnet mask. ...
Class C = 192.0.0.x 223.255.255.x 255.255.255.0 The subnet mask filters out the network bits by using ANDing. ANDing takes the IP address in binary value and uses the binary value of the subnet mask to determine the bits that are left as one or 'active'. This is accomplished by taki...

Subnet masks such as 4 and 60 are not recommended Subnet mask and IP address combination, you can distinguish a network address of the network number and host number. For example, there is a class C address of: 3, with its IP address type, whose default subnet mask is: , then its ...
