Here's one way to achieve your goal:

@Echo Off
Set "IP="
For /F "Delims=" %%A In ('IPConfig^|Find "IPv4"') Do Set "IP=%%A"
If Not Defined IP GoTo :EOF
Set "IP=%IP:*: =%"
Echo( Local variable %%IP%% resolves to %IP%
Timeout -1
GoTo :EOF

Spaces are significant on both sides of the = in a set

remove the spaces.

In order to reference the contents of a variable var you need to use %var%

Batch simply continues line-by-line until it reaches a goto or end-of-file. It has no concept of "procedures." Having executed your for, it will continue and once again execute the set and echo. You need a line

goto :eof

before the label :foo. This instruction goes to end-of-file (the colon in this case is required)
