	Well as you can see 28.84.IN-ADDR.ARPA is delegated to
	NS.RIPE.NET however it isn't serving it.  The other
	nameservers for 28.84.IN-ADDR.ARPA are serving it.

	Either NS.RIPE.NET needs to be fixed, the zone contents
	needs to be fixed or the delegation needs to be fixed.

	I suggest you contact the administators of 28.84.IN-ADDR.ARPA
	and get them to address the problem.

	Mark
