Description:

The IP Subnet Calculator is a popular freeware Windows 95/98/NT/2000 utility for computing information about IP addresses. Refined over the years, the IP Subnet Calculator is now in its third release, and is also part of our commercial product, the multi-purpose Network Calculator.

Features

Given an IP class A, B or C address, several pieces of information can be displayed about that address by selecting one of four tabs:

• Address Info Tab - displays the class of address and range of addresses for that class, a color-coded bit map for that class of address, the binary representation of that address, and the hexadecimal representation of the address.
• Subnet Info Tab - allows you to enter subnet information in five different ways: by number of subnet bits, number of total mask bits, number of subnets, number of hosts, or just the subnet mask in dotted decimal notation. For the information entered, the Calculator generates a color-coded bit map breaking down the network, subnet and host portion, shows you the subnet host address range, the subnet ID and subnet broadcast address.
• Subnet/Hosts Tab - generates a table showing the subnet ID, host range of IP addresses, and the subnet broadcast address over a range of user-selectable subnets.
• CIDR (Classless Inter-Domain Routing) Tab - is particularly interesting for ISPs or corporations with many Class C addresses as it displays information on supernetting (collecting multiple IP addresses together). Within the CIDR Tab, you can enter an IP address and the number of supernet bits you wish to use, and the Calculator will display the number of possible supernets and their address allocation range. The route address and supernet masks used are displayed in dotted decimal and dotted hexadecimal notation.
