Comment:

 I think we can consider using this for a few small situations where it is
 likely to be safe and stable to use and gives better performance than our
 current solutions:

  * IP Address filtering - faster than the regular expression based
 solution we have now
  * is_email - better coverage than our current solution.

 If someone was to create a patch for this that would be great - this
 includes creating a new IP address sanitisation wrapper function to
 replace the duplicated preg_ code we have at the moment.
