I can't send emails to AOL etc. I have contacted my ISP (
I have a T1 to the internet via SBC) and told them to do
the reverse stuff on there side. I got a confirmation
this morning saying it was done. I host my own Exchange
server and I am told that I have to setup reverse DNS for
it to work. I can't seem to get it setup right. I still
can't send AOL emails and when I go to DNSREPORT.com is
still shows that my reverse DNS is not setup. Can anyone
provide assistance? I have a Windows 2000 enviroment.
thanks in advance.

Patience grasshopper. If you just got them to do it this morning, it may
take upto 72 hours for it to take effect.

SBC is your provider?
Does SBC host the Forward Lookup zone?
If they don't host the forward zone, they can't host the reverse. That is
the story I got from them, they'll be glad to delegate it for you to another
DNS.
 
here is a copy of what SBC sent me:

Your DNS request is complete. Below is a copy of
the zone for both IP blocks. Please contact us if you have
further questions. I need to know how to setup a reverse
dns for 66.140.116.5 which is my exchange server.

They have not created a reverse lookup, they have done what I said they
would do delegate it to another DNS server. In this case ns67.worldnic.com.

ns2.swbell.net says to go to NS67.WORLDNIC.COM. (zone:
0.116.140.66.in-addr.arpa.)

For this to work you will need a reverse lookup zone
named "0.116.140.66.in-addr.arpa." (without the quotes) on the noted DNS
above with your PTR records in it.

SBC will _not_ create a reverse lookup if they do not host the Forward
lookup. This I know first hand.

Take a look:
http://www.dnsstuff.com/tools/ptr.ch?ip=66.140.116.5
 
So, all I need to do is create a new zone under the
reverse folder called 0.116.140.66.in-addr.arpa. and thats
it?

That has to be done on the DNS server they delegated it to, which is
NS67.WORLDNIC.COM. whomever the admin for that DNS server, needs to create
the zone and PTR record.

If NS67.WORLDNIC.COM is you then, yes, you create the zone. But, something
tells me that is not your DNS. Below is what I get on the DNS it is
delegated to.
NS67.WORLDNIC.COM. a

I found out I need to set the DNS on my side.
Do you have any idea where I need to start? Do I just
create a new zone and name it? thanks for the help.

Just creating the zone won't help, the zone has to be on the DNS server SBC
has delegated the zone to, in this case I'm sure it is not you.

If you want SBC to delegate the reverse zone to you, first things you'll
need to do is get your registrar to create a DNS Host with the public IP of
your DNS server.
Then you'll have to allow incoming connections on 53 TCP and UDP on the IP
and forward them to the IP of the DNS server.
Then after the host your registrar has created has propagated, call SBC and
have them change the delegation to the host and IP that your registrar
created.

You'd be better if you let the admin of the current DNS it is delegated to
create the zone, but that is only my opinion, you know how opinions are.
 
In
When I make the DNS change will it take affect immediatley
or will it take a while to propagate?
Click to expand...

If the zone is delegated to your DNS or any others, when you make any
changes, deletions or additions, there is a 24 to 72 hour propogation wait
period.

But as Kevin said, it's probably alot easier to let your ISP take care of,
which in this case is whomever owns worlnic's nameserver, but it sounds like
Network Solutions. Curious, why did they delegate it to that and not to your
DNS, unless you didn't ask them specifically?

Hi Ace,
Just a guess here, but sbaker probably didn't specify who to delegate it to,
they probably delegated it to the Authoritative DNS for his forward lookup.

I had this problem with SBC, they were hosting my forward zone and reverse
lookup. When I moved my Forward lookup, their DNS server automatically
deleted the reverse lookup. When I called them about it the said they have
to host the Forward zone before they can host the reverse zone. Personally I
think it's mostly a money thing, they don't charge for hosting, they do
charge for setup, $100 per domain and $50 for changes.

They have to host the Forward first? That's ludicrious!! What a scheme! LOL.
I used to use Qwest and I did not host any one of the 25 domains I was
hosting with them at all. But they did delegate the reverse to my two name
servers with no problems. I had the whole IP 'C' block.

I would look for another provider... :-)

Not much choice, it's either SBC DSL or Cable, don't want cable, I think
they're more than DSL.

Unfortunate. How much is cable?
But then again with cable, its tough running different services, especially
mail.

44.95 if you have Cable TV 54.95 if you don't. (I Don't) Cable would be
another 50.00 a month.

My DSL is 64.95 with 5 IPs and no restrictions on the services I run.
I could get DSL for 44.95 with a dynamic IP.
Oh, and of course who can live without a telephone.

I can understand your choice and would have done the same thing. Tell you
the truth I'm sick and tired of Comcast. Mine is 42.95 with and 54.95
without cable. I think they'll be raising it soon. If I can get some things
that I have going on in the works in gear, I may go back to a T1. :-)

Yes, and I didn't even mention the restrictions put on cable internet, I was
looking at the terms of use earlier, there is no way I'd ever go to cable.
It would have to be dam cheap, no servers no public services, cable is way
to pricey for that the little dab I get off my services helps pay my bill
and the phone co doesn't care if I keep my line maxxed out 24/7, I'm sure
the way they look at it if I don't have enough bandwith for what I'm doing
they'll sell me some more. Which I may just do, I can go one step higher on
DSL, if that gets too conjested they'll gladly sell me a T1. I think before
I do that I'll set up downtown. One of my clients are downtown he has the
same tier as I do but because he is only two blocks from the CO his average
down is 1.9Meg and 220k up (it supposed to be 1.5m and 128k)

128k up is kind of slow. And you;re right, there are numerous restrictions
with Cable. Can't run crap on here. You know what's funny? Their mail
servers don't need authentication to relay from their own subnets. I wonder
how many are spamming thru it? LOL. I don't use my account with their mail
system, but did notice that little tidbit. :-)

One thing I can say good about Comcast (about the only thing actually) is
the up speed is 256k, but the down speed is 3mbps. I'm hosting my servers
currently at a friend's T1 for a great reasonable price. I had SDSL 1.1m in
the past, and I liked it at $295/mo. I couldn't get any faster because of my
distance at 11,300' from the CO.

Dear Kevin,

On a different subject:

I have clients who use thier fax lines for SBC DSL.
From your comments, I am wondering if I can
use a home phone line (voice) as a DSL line at the same time,
or, once having turned it into a DSL line will it still work
as a voice phone line as well?

Thank you,
James W. Long.
