IP Subnet Calculator
Network IP calculator

The IP Subnet Calculator is a utility for computing information about IP addresses. 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: the Address Info, Subnet Info, Subnet/Hosts or CIDR tab.
The 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.
The 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.
IP Subnet 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.

Ping Plotter 1
Enhanced trace route program

Ping Plotter is an enhanced trace route program. It does all the things a normal trace route program does - just faster.
It also adds some great features (graphing, enhanced statistics, etc.).
Basically, Ping Plotter is a trace route program - but adds some graphs, plus some serious performance upgrades.
It uses the multi-threading capabilities of Windows to check performance on all hops in the route at the same time.
This has several advantages: 1) It s a lot faster. 2) All hops are tested at the same time - rather than many seconds apart - so the comparison is better.
Another advantage of Ping Plotter is that you can set it to a continuous mode - where it will test the same route over and over again - forever if you want. That way you can watch the performance over a period of time without having to re-run the program over and over again.
