The Subnet Calculator enables subnet network calculations usingnetwork class, IP address, subnet mask, subnet bits, mask bits,maximum required IP subnets and maximum required hosts per subnet.Results of the subnet calculation provide the hexadecimal IPaddress, the wildcard mask, for use with ACL (Access ControlLists), subnet ID, broadcast address, the subnet address range forthe resulting subnet network and a subnet bitmap. ==Notes about theSubnet Calculator======== 1. The subnet calculator implements aclassful / classed IP addressing scheme where the following rulesare adhered 2. The subnet calculator allows the use of a singlesubnet bit - for example, a class C address with a subnet mask of255.255.255.128 is permitted. 3. The subnet calculator allows asubnet ID to have its final octet equal to the final octet of itssubnet mask - for example, a class C network address of192.168.0.192 with a subnet mask of 255.255.255.192 is permitted.==Subnet Calculator - Network Tools Feature Overview======== 1.subnet save and load 2. Network Address, Broadcast Address, FirstAddress, the Last Address real-time output 3. Calculation ofreal-time subnet using the slider
