Reverse DNS for telecom gear (routers, switches, etc.) still makes sense
IMO, because it demonstrably aids network troubleshooting. But I think
we should stop recommending it for end nodes. End-node reverse DNS just
nourishes the myth that you can reliably tell who/where/what
something/someone is just by doing a reverse lookup on their source
address, a myth from whence springs wrongheaded security methodologies,
bogus "traffic-shaping" schemes and similar balderdash. More concisely,
I think end-node reverse DNS fails cost/benefit analysis.
