Substitute the subnet bits in the binary classification and we get 11111111.11111111.11111111.

Step 6: Use the bits calculated in the above step, to compose the subnet mask in binary form using the default binary classification. Step 5: Given here is 6 subnets, Applying the values in the formula, we get, Number of Bits = Log2(Number of subnets + 2) = Log2(6+2) = 3 bits. Step 4: Formula to calculate Number of bits = Log2(Number of subnets + 2). This IP subnet calculator covers both IPv4 and IPv6 protocols, providing information such as IP address, network address, subnet mask, IP range, and more. You are usually pretty safe using 255.255.255.0 for your. With this calculator you can calculate subnet IP address by getting one of existing subnet IP host addresses. Determining the proper mask value to assign to router and client IP addresses is sometimes difficult. Step 3: Calculate Number of bits, to define the subnets. Subnet IP Address Calculator subnet ip calculator in c++. ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. Step 2: As the IP starts with 192, the address falls on Class C. 192.168.91.254) : Please give me your first IP address in your range (i.e. Step 1: Determine the network class of the given IP Address 192.35.128.93. SubnetMask Calculator Please give me your last IP address in your range (i.e. 11111111.11111111.11111111.00000000 (Class C, network part is 24 bits)įor example let us consider an IP address 192.35.128.93 which belongs to the network with 6 subnets. Online utility for IP address calculations including netmask, broadcast and network addresses, wildcard mask, usable ranges, address format conversion etc.
