+ * This case is the be all and end all patch to catch and nuke 4in6
+ * instead of special-casing shit all over the place and wreaking merry
+ * havoc with crap, instead, we just recreate sockaddr and strip ::ffff: prefix
+ * if it's a 4in6 IP.
+ *
+ * This is, of course, much improved over the older way of handling this
+ * (pretend it doesn't exist + hack around it -- yes, both were done!)
+ *
+ * Big, big thanks to danieldg for his work on this.
