Added a function validateipaddr() use as:

// Validate a network address
//	$addr: the address to validate
//	$type: IPV4|IPV6|IPV4V6
//	$label: the label used by the GUI to display this value. Required to compose an error message
//	$err_msg: pointer to the callers error message array so that error messages can be added to it here
//	$alias: are aliases permitted for this address?
function validateipaddr(&$addr, $type, $label, &$err_msg, $alias=false)

This is indented to provide a single method of validating IP addresses of all types and composing a suitable error message
