Steps to reproduce

Typing ip shows ipconfig as a suggested auto-completion. However, when pressing TAB it auto-completes it to ipal

Expected behavior

Pressing TAB button when presented with auto-complete should fill in the rest with what we are presented with.

Actual behavior

Pressing TAB button when presented with auto-complete instead fills it to a random cmdlet it thinks is correct, which is what happens on PowerShell 5.1.

That's not tab completion, it's prediction. The standard way to accept predictions is the right arrow key, you can bind it to Tab like this: Set-PSReadLineKeyHandler -Function AcceptSuggestion -Chord Tab but then you won't have your standard tab completion so I'd advice against it.

You're seeing IPConfig because that was the most recent command beginning with IP that you used. If I type IP I get IPMO module name

As @MartinGC94 says tab cycles through all commands beginning IP in alphabetical order, right arrow pulls back the whole of the line by default (so If you had ipconfig /flushdns you'd get the switch) In my profile I've set ctrl right arrow to pull back a word at a time, which IMHO makes the feature significantly more useful.
