Follow and show every hop in a URL's redirect chain.

Check whether a site is up, its HTTP status and response time.

Check if a website is up or down right now, with its status code and response time.

Fetch the HTTP response headers and status of a URL.

Test whether a TCP port is open on a host.

Measure round-trip latency and packet loss to a host.

Trace the network path (hops) from this server to a host.
