What it is for

Use it to answer whether an address, a route, or a listening socket is what you expected. Test-NetConnection is the quickest way to separate a name resolution problem from a port reachability problem in a single call.

Typical tasks

List IPv4 addresses per interface
Inspect the default route and its metric
Find which process owns a listening port
Test a TCP port against a remote host
Group established connections by remote address
Check for duplicate or tentative addresses

Check the installed version

1PS> Get-Module -ListAvailable NetTCPIP | Select-Object Name, Version, Path

2PS> Get-Command -Module NetTCPIP

Compare the module path and version with the session used by your scheduled task or automation account. Use it to answer whether an address, a route, or a listening socket is what you expected. Test-NetConnection is the quickest way to separate a name resolution problem from a port reachability problem in a single call.
