Re: [IMail Forum] PTR Record Problem on Wednesday 8:54:01 AM
Scott, if I go to http://www.DNSstuff.com it shows that I have a
PTR reverse problem on 208.45.107.202 when I run my own primary
DNS with secondary at Qwest. This seems to come up awful fast,
and I was wondering if it isn't seeing my reverse because it is
timing out on the lookup too fast. My reverse are there and can
be seen with a simple or trace on most remote systems.
http://www.dnsstuff.com/tools/ip4r.ch?ip=208.45.107.202 is the
test I am using.
Since this subject came up here, I thought I would ask. Am I
missing something here?

R> has a reverse DNS entry listed in it, and my example.com domain works just
R> fine"). Then, they "prove" it by saying "If I type 'tracert
R> xxx.xxx.xxx.xxx' from the local network, it shows the reverse DNS entry'
R> (since the local network typically uses the local DNS server, it will see
R> the reverse DNS entry).
R> I would strongly urge people (even the person who posted the recommendation
R> for zoneedit.com) who think that they have a reverse DNS entry set up to
R> verify that they do. One way is through our http://www.DNSstuff.com site,
R> using the "Reverse DNS Lookup" tool. You may be surprised to find out that
R> there really is no reverse DNS entry. Remember, the key is that your ISP
R> or bandwidth provider (whoever originally gave you your IP address)
R> absolutely, positively must take some action for the reverse DNS entry to
R> work -- there is no way around that. And, in many cases, the ISP makes a
R> mistake (as someone reported earlier today), so you still need to
R> double-check their work.
