What is a network diagnostic tool?

A network diagnostic tool tests connectivity, latency, routing, and service availability on a network. It helps identify where failures occur in the network path.

What does a traceroute show?

A traceroute shows the complete path that packets take from your computer to a destination, listing every router hop and the latency at each step.

How do I check if a port is open?

Use the port scan feature in NetSpidey Network Tools. Enter a hostname or IP address and a port number. The tool attempts a TCP connection and reports whether the port is open, closed, or filtered.
