01Command
$ ipconfig /all02What it does
Plain `ipconfig` only shows the essentials; the /all switch adds DHCP status, lease times, DNS servers, the MAC address and the host name. This is usually the first command to run when diagnosing why a PC cannot reach the internet. In PowerShell, `Get-NetIPInterface` and `Get-NetIPAddress` offer similar data in object form.
