This module collects IP validation routines to make input validation, and

untainting easier and more readable.

All functions return an untainted value if the test passes, and undef if it
|
|
|
|
|
fails. This means that you should always check for a defined status
|
|
|
|
|
explicitly. Don't assume the return will be true. (e.g. is_username('0'))
|
|
|
|
|
|
|
|
|
|
The value to test is always the first (and often only) argument.
