Detailed Description

This uses QHostAddress internally to check if the field contains a valid IP address. You can use the constraints flags to limit the validator to specific address ranges.

Note: Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. If the field's value is empty or if the field is missing in the input data, the validation will succeed without performing the validation itself. Use one of the required validators to require the field to be present and not empty.

See also: Validator for general usage of validators.
