-InterNIC/ARIN designates DNS to IP's
-Your upstream's upstream carries the Reverse Authority, pointed to your
upstream.
-Your upstream points Reverse Authotiry to you.
That is a trickle-down approach, very inconvenient and unreliable. I have
heard that "you can't register just one class C for reverse DNS." That is
incorrect, you can and it should be done, unless you carry more than a
class C all your own. They should be registered in the largest blocks
appropriate.
Sorry if I just confused anyone, I can write a longer explanation if need
be...

<excerpt><smaller>So far, I have figured out Microsoft DNS, mostly. When
it comes to the reverse DNS look up though for A records I am hesitant to
add them. Currently I only have 2 A records that do not have an
associated PTR record in the in-addr.arpa file. In the properties of
these A records, it says to update the associated PTR file. Should I go
ahead and add these PTR files so reverse DNS can take place?
