Feel free to download the subnet mask quick reference and also copy down the above example on how to calculate subnet mask manually. 252.0 as the subnet mask in the network that we need 1000’s PCīase on the above diagram, subnet mask quick reference, you are able to decide what is the subnet mask that suitable your company or your network need.Įxample your computer require 4000’s PC, refer to the MAX HOST above, look for the 4096 Max Host, and the subnet mask are 255.255.240.0 without calculate subnet mask manually.Īs above experience on my client side networking setting, now I know how to use suitable setting for the subnet mask in the future. /24 255.255.255.0 256 Hosts 1 Subnet 255 1 Split the box in half and you get.
#Wan subnet 255 255 255 252 code
The binary code for the subnet mask should be : 1 0000000, we categories this binary as ,īelow are the table on calculate subnet mask for:Īs above situation in my client side, they need 1000 PC’s, base on the formula above stated, IP addressing and subnetting formulas require detailed calculations in order to.

128), when we require not more then 126’s PC in the network.įor 255.255.255. Normally for class C IP address, we will put the subnet mask as 255.255.255.0, but some other case, they are putting 255.255.255. I was confuse, why set to 252 instead of 255?Īfter Re-attend my CCNA class, CCNA in Penang, I understand how this work and also get the method on how to calculate subnet mask. First bits determine the class of your network from A to E. We can see two things: all host bits are zeroes in a network address, in a broadcast address they are all set. I have to assist them to change the setting in their 3Com manageable switches. This free online IPv4 subnet calculator also can be used as a teaching tool and presents the subnetting results as easy-to-understand binary values. A network is called a subnet when the prefix boundary contains more bits than the network's. For example, a single 192.168.16.0/24 address range can be split into two by extending the subnet mask by borrowing one bit, transforming the subnet mask from a /24 to a /25 or a 255.255.255.128 in decimal notation. They require to change the subnet mask in all their computer, server, and manageable switch. They do this by extending the subnet mask by borrowing host bits from the designated host range. How to calculate Subnet mask, Calculate Variable Length Subnet Mask (VLSM)įew week back I face one confusion when one of our client require to increase their company computer from 200 to 1000’s PC, in the near future. The network drawing above shows the IP address map for a WAN installation carried out for.
