Setting up rDNS

I am having trouble setting up rDNS on my end (data center already set-up rDNS for my server on their end over 72hrs ago).

The main IP to my server is: 64.71.173.95
The IP block assigned to me for rDNS is: 64.62.249.106/29
My main domain is: soychicano.com
With name servers: ns.soychicano.com and ns2.soychicano.com

In my /etc/named.conf file I appended:


I created the file: /var/named/249.62.64.in-addr.arpa
and added:



However when I try to do a reverse DNS lookup ( http://dnsstuff.com/tools/ptr.ch?ip=64.71.173.95 ) it doesn't return the domain name. What am I doing wrong? Do I have to wait for the new settings I made to propagate? I would assume not.

(NOTICE: the ip address in your dnsStuff link does not match the zone you provided)

There were 3 dns host servers returned in in the following query:

http://serialcoders.sytes.net/cgi-b...&lr=1&submit=DS

By clicking on the first purple link, you send the query to the first server:

http://serialcoders.sytes.net/cgi-b...e=PTR&submit=DS

I recieved a CNAME as you can see in the link above.

By clicking on the second purple link, you send the query to the second server:

http://serialcoders.sytes.net/cgi-b...e=PTR&submit=DS

I recieved the same CNAME.

By clicking on the third purple link, you send the query to the third server:

http://serialcoders.sytes.net/cgi-b...e=PTR&submit=DS

UDP request timed out. Perhaps the server is offline, or the IP has a typo, or a router/firewall blocking the request.

Going back to the first purple link, I click on the blue link for the CNAME domain:

http://serialcoders.sytes.net/cgi-b...&lr=4&submit=DS

It practically goes into an infinite loop looking for an authoritative answer, but is halted by the limitation of "Local Recursion" I have in my script. In english, I could not resolve the domain in the CNAME.

So the code I provided is not correct?




If its going into a loop, I'm betting that it's becaused I didn't configure it right...perhaps something to do w/ the fact that the zones dont match? Can you confirm that the code i provided *is* correct?

This zone: 106.249.62.64.in-addr.arpa

Does not cover this IP: 64.71.173.95

This IP: 64.71.173.95

Is not located in this IP block:

So what are you trying to configure? your post disagrees with itself as to what you are wanting to do. Do you want to create a zone for this IP block "64.62.249.*" or do you want to create a zone for this IP "64.71.173.95"?

Well, 64.71.173.95 is the IP of the server. When I requested rDNS be set-up on it, they gave me IP block 64.62.249.106/29. Not having messed around w/ all this, I am not sure what to do w/ that block of IPs assigned to me when I requested rDNS. Do I have to somehow change the main IP of my server to one in this new block? Or leave that IP as it is and just do some configurations on the new block of IPs?

I want to be able to have rDNS set-up so that 64.71.173.95 points to soychicano.com as that IP has been blocked by some ISPs and I can'ts end e-mail to them. One of these ISPs is AOL and I contacted them and they said I must have rDNS set-up before they can take off my IP from their blacklist.

Well, I don't know anything about rDNS or a block IP's, but this is what I do know.

Email servers may reject email from client computers that don't have a reverse lookup configured for their IP address that matches with their sending domain. Here's how it works:

Client Name = mail.letmesend.com
Client IP = 127.0.0.1

Server Name = mail.evilaol.com
Server IP = 192.168.1.2

So SMTP transactions begin (paraphrased):

Server-->This is a SMTP server, hello, evil aol owns me
Client-->HELO mail.letmesend.com

Client identified itself as "mail.letmesend.com". At this point, 'Server' will look up "127.0.0.1" since that is where the client is connecting from. If the "127.0.0.1" returns "mail.letmesend.com" then the server can feel pretty secure that you are a legitimate mail server sending the email rather than a spammer.

So the trick is... you need to change what a lookup for your IP returns. The following are the dns servers that host your IP information:

http://serialcoders.sytes.net/cgi-b...&lr=1&submit=DS

Clicking any of the purple links will ask the associated server if it knows the domain for that IP address. However, they'll all respond with "Name Not Found". So nothing is configured for that IP address.

So if you have access to your IP records on those dns hosts, then change them. Otherwise, if the IP belongs to your ISP, then contact your ISP about setting your IP address to your mail server domain.

(if you still want help with what you've asked previously, ask again. This post is an answer to your problem, rather than an answer to your specific questions)

I only have root access to 64.71.173.95. I assume the dns hosts you're refering to where I need to change the IP records are ns[1-3].he.net? No I don't have access to that. But I spoke to them and they said they had configured it on their side. All I had to do was configure it on my side. How can I check what they configured for 64.71.173.95 and 64.62.249.106 (if anything)?

The ns servers you speak of has configured something for the "64.62.249.106" IP address. They have CNAMEed it to another domain called "106.subnet104.249.62.64.IN-ADDR.ARPA" which apparently you are supposed to be hosting. I have no clue why they did it this way. It is very messy.

But for proper reverse resolution for that IP address you need the following:

[named.conf]


[subnet104.249.62.64.in-addr.arpa]


However, those ns servers have nothing that handles the IP address 64.71.173.95.

That's why I wondered why I was given a block of IPs when i requested rDNS. I tried the code you provided but still didn't work. Maybe he.net didn't set it up right?

either you have not restarted or reloaded BIND, or you misconfigured the zone file, or you misspelled file names.
