Have you checked the types being operated on? I'm wondering if somehow one
of the object properties you're operating on has changed has changed in
terms of type.

I'd try var_dumping each of the properties ($this->network and
$this->netmask) the line above just to make sure they didn't somehow get
switched to a type that bitwise operators complain about (array, Object.)
