Pingplotter & MultiPing
Pingplotter combines basic Ping and Traceroute commands into an easy to use graphical interface. Advantages of using Pingplotter are many. It will perform multiple traces to whatever destination you specify, then combine and graph the results. The graph including an average trend line, with min, max, and last results plotted on the line. Recently traced addresses are stored in the history on the left, saving you typing for addresses you check frequently. Export results as text, or as an image of the plot. Pingplotter has become the first tool I use when I suspect a system is in trouble.

Angry IP Scanner
Angry IP Scanner is another fast, lightweight tool. It requires no installation and is easy to use. Enter the IP range you want to scan and click Start. In a few moments you will have a list of all the devices on the network, including hostnames and open ports. Here is a list of possible uses:

• Scan your network to see if anyone has plugged in unauthorized devices - like rogue WiFi access-points
• Do you have building electrical maintenance planned? Instruct your users to shut down when they go home, then scan the network to see if any machines were accidentally left on
• Use the port scan to do a basic check for possible vulnerabilities, or see if someone has installed web or mail servers that you don’t know about
• Check to see how many free IP addresses you have on a subnet, then optimize your DHCP scope.
