210.146.35.35 stepped through our entire 128.219/16=20
address space yesterday asking for reverse DNS lookups. =20
It started at 16:06 and ended at 20:34. This is the=20
equivalent of a zone transfer.=20
=20
I'm looking for a clever way of stopping this. And if we=20
can't, we want to at least slow it down. Creating dummy=20
records for the unused IP addresses has not been effective. =20
*Any* ideas you have would be most welcome.
