![]() Network security concerns caused by secured and unsecured servers using the same subnetĪ subnet mask is a 32-digit number determining the possible range of IP addresses available in a network.One subnet mask limits how many IP addresses can exist on a single network, but multiple subnet masks can be used to organize an entire network into sub-subnets.Ī subnet mask also indicates which part of the IP address refers to the host and which part refers to the subnet. Class A, B, and C networks have default masks, and an IP address on an unsubnetted Class A, B, or C network would have an address/subnet mask pair similar to the default mask. To find which part is the host and which part is the subnet, you must convert both numbers to binary numbers. This makes it easier to differentiate the host from the subnet. #Solarw subnetcalc code#Īddress bits corresponding to 1 in the IP class’s default mask represent the subnet, and address bits corresponding to a 0 in the default mask represent the host.īy using CIDR notation, our subnet mask calculator can help you easily find the subnet mask-no binary code conversion necessary. ![]() You should use a network subnet calculator to subnet your network for three primary reasons. ![]() Organizational Efficiency: When it comes to partitioning a large enterprise’s network and dividing resources accordingly, subnetting the network gives you several different options. ![]()
