Ping lets you test TCP/IP connection quality between your computer and servers both on local network and the Internet. Rather than using ICMP that is blocked by many firewalls, Jujuba Software Ping actually establishes TCP/IP connection and exchanges data with the server to measure packet loss percentage and round-trip time accurate to 0.01 milliseconds. Ping works great on both IPv4 and IPv6 networks. It allows you to ping several hosts at the same time and displays data in highly visual and intuitive manner.
