In this Excel VBA tutorial, we will be creating a User-Defined Function (aka UDF) to validate if IP addresses are valid.

Assuming you have a spreadsheets with a list of IP addresses, and your job is to validate whether each IP address is valid. My personal experience with writing a formula for such task is a bit cumbersome and complicated. Using VBA to create our own function can simplify the process and we can also export the function as an add-in for future use.
