Or in any case, it's not sufficiently different to cause an interoperation problem in this case. The reference to RFC2821, section 10.2 was regarding the fact that having multiple PTR records for one address *IS* legal, despite widespread belief to the contrary. The original point was that you'll need a router ACL to block a lot more than one address, and keep the list of addresses up to date. And anyhow, using a router block is a bad idea in this case. There's two cases - either you still have machines using that vendor's software, and you WANT them to reach the servers so they can update, or you don't have the software installed, in which case you don't really care if the server is reachable.. -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
