This is the new ipconfig for PowerShell.
Here is the example for the straight gip command.
Here is gip with the -detailed option shortened to -det.
Isn't that great!
It might not be THE BEST PowerShell alias, but it is up there. I think GCM would take that crown.
[Update] I just did a search and found a TechNet blog article about GIP and also TNC. TNC is an alias for Test-NetConnection and looks like a great alias also. Read the article New Networking Diagnostics.
