I am trying to set up reverse-DNS for all of my dialup IP addresses in =
Windows NT's DNS Manager, but I am not sure if I am doing it correctly.
I thought all I had to do was create A records for each IP address and =
make sure that an "associated PTR record" was also created. I did that, =
but when I look up the "x.x.x.in-addr.arpa" records, some of the PTR =
records are duplicated, and some are missing entirely. I tried adding =
the missing ones and deleting the duplicates, but after doing that, some =
OTHER PTR records became duplicated and others were missing. It wasn't =
due to my overlooking them, either, because I was working pretty =
systematically. I decided not to mess with it further, since I didn't =
understand what was going on and didn't want to create a larger mess. =20
Now when some of my users dial in, they say they still don't get a =
reversable IP.
Do you know how to verify that a given IP address does in fact have =
reverse-DNS enabled (without dialing in myself until I get assigned each =
and every one of the dynamically assigned IP's)? Or how to do it right, =
if I am in fact messing something up?
Thanks for any advice anyone can supply. =20
