Are you a network administrator who need to calculator and assign IP address for your workstations and servers or view the subnet host address range of your network It is not an easy job for ordinary users or beginners to calculate their subnet configuration. Want to manage your network as easy as possible The IP address calculator is a great assistant for you. Here I will recommend a powerful yet easy-to-use IP address calculation tools to you. That is Advanced IP Address Calculator which was published by Famatech International Corp. Following is the detailed introduction of this network administrator tool.

Advanced IP Address Calculator is an easy-to-use IP subnet calculator that lets us to calculate every aspect of our subnet configuration in a few mouse clicks! The calculator generates a color-coded bit map, breaking down the network, subnet, and host portion. For the information entered, the calculator generates a color-coded bit map breaking down the network, subnet and host portion, shows us the subnet host address range, the subnet ID and subnet broadcast address. Important features like CIDR (Classless Inter-Domain Routing), the binary representation and hexadecimal representations of IP addresses are supported. The interface of this software is very compact and simple. The detailed functions and provided information of each item including:

1. IP - In this edit box, enter an IP address and it is automatically validated according to subnet IP rules. For example, the first IP digits cannot be less than 1 or greater than 224. If we enter an invalid IP, it is automatically changed to a valid address.

2. Network type - Classes 'A', 'B', 'C' and 'D' are supported. The first three network classes determine the number of bits used for subnet generation and class 'D' network is reserved for multicast. The difference between these network types is in the number of bits that can be used for subnets and hosts. For example, for an 'A' class network you can use 24 bits for subnets and hosts and we can select any address within the range 1.0.0.0 - 126.255.255.255.

3. Binary - This field displays the binary IP representation using colored digits, so the roles of the individual segments are shown. Each color represents a different part of the IP: the network prefix, subnet number and host number. The network number is the first 8, 16 or 24 bits (depending on the "Network Class" ), that determines an address of our network. The subnet number is the next array of bits that determines the quantity of subnets. For example, if we have two subnet bits, we can use four networks with these bits set to 00, 01, 10, and 11. Note that if "Allow 1 subnet bit" is checked, the first subnet bit will always be 1. So we will get only two subnets - 10 and 11. Host bits determine the range of IP's that can be used in each of the subnets. For example, three subnet bits will result in IP's with the last bits of 001, 010, 011, 100, 101, 110, i.e. six IP's. The 000 and 111 are used for ID and broadcast.

4. "HEX" / "BIN" button - This button switches between binary and hexadecimal IP representations.

5. Mask - We can choose a valid network mask for a current network class. Press the "invert mask" button to see an inverted mask used in some programs.

6. Hosts - This field shows us the range of all available hosts (in all subnets) that can be used in a current network configuration. Press the "look at hosts" button to see a list of all the available hosts.

7. Subnet ID - The "ID" that is assigned to a current subnet. This is the first host in a subnet.

8. Broadcast Address - The broadcast address for a current IP address and mask. This is the last host in a subnet.

9. Multicast Address - If a 'D' class network is selected, this field contains its multicast address.

10. Subnet Bits - Select the number of bits for a subnet. Look at the binary IP field to see a visual representation of the changes we make.

11. Mask Bits - Select the number of bits for a subnet mask. Look at the binary IP field to see a visual representation of the changes made.

12. Mask Subnets - Select the maximum number of subnets that can be generated using the current network configuration. Look at the binary IP field to see a visual representation of the changes made.

13. Mask Hosts - Select the maximum number of hosts that can be generated using the current network configuration. Look at the binary IP field to see a visual representation of the changes we make.

14. Allows One Subnet Bit - In some networks the subnet cannot be described with less than two bits. Use this checkbox to allow or forbid "using only 1 bit" as a subnet identifier.

15. Supernet Mask - Choose a supernet mask and it is validated for the current network configuration.

16. Supernet Mask Bits, Max Supernets, Max Supernet Addresses - Use these parameters to configure our supernet settings.

17. Route - Displays the supernet route to a target IP address.

18. Supernet Address Range - Address range for all valid supernets within a current network configuration.
