Does revers DNS apply for server or each virtual hosting?

thanks

Reverse dns applies to each IP address, that's the only thing that will do a reverse query.

I'm not sure if I answered the question (not entirely sure if I understood the question).

But something like an apache vhost will probably have the reverse lookup be your hosts name.

I am confused with few Reverse DNS with some thread there.

Reverse dns mean when you type IP address on the browser it will go to the domain right.

I mean IP to host.

Am I right?

Thanks

Reverse dns is when you lookup an IP and it productes a name, IP > Name

Forward dns is when you lookup a domain and it returns the IP.

Reverse dns, you can have only one IP to a one name. Forward, you can have many names to an IP.

Hope that helps.

No, it means that when you do a DNS lookup for an IP it will come up with the host name.

for example

nslookup www.webhostingtalk.com will give you 207.218.223.148

and

nslookup 207.218.223.148 will give you panther1.webhostingtalk.com, which is the real name for that host.

I hope this helps.

Thanks guys.

if it comes

]nslookup 69.xx.xx.xx

Server: 127.0.0.1
Address: 127.0.0.1#53

** server can't find xx.xx.xx.69.in-addr.arpa: SERVFAIL

It means that there is no reverse dns setup right?

Thanks

Either not setup, or setup incorrectly.

The other thing that comes to mind is whether you have reverse dns control delegated to you or not. That's an issue you'd have to find out from your upstream provider.

Do you mean ISP of my server or root of the name server?

Thanks

Yes you can. but you must said to upstream provider... for your's ip can delegation to your's DNS box... and then you must add one by one IP for each virtualhosting.

After Upstream provider enabled the reverse dns. What should I have to do to in my server?

if you have an expampled please let me know.


Thanks all of you.

what is purpose for setting up reverse dns?

when i nslookup my ip it does return my host name but i do not know what is it and what would be the problem if reverse dns is not setup.

To check who reverse DNS is delegated to, use
nslookup type=NS xx.xx.xx.in-addr.arpa, replacing the xx's with the standard arpa notation for the class C you're looking up. :)

Where could we set up reverse DNS on the Fastservers.net dedicated servers?
Do we need to ask he.net for setting up?

Hi,

I understand some of the mail server request reverse dns
to receive a mail. If i do the reverse dns for main IP address of the server then it should be able to receive mail.

Anyone has any suggestions.

Thanks

FYI, there really is no such thing as "reverse DNS".

The term "reverse DNS", although a misnomer, is commonly used to mean doing a "non-reverse" lookup on the infrastructure in-addr.arpa domain.

Hi,

If my upstream provider did reverse lookup for IP, what should I have to do in order to make reverse lookup.

Hi,

This is how I set up Reverse Dns on my server and still doesn't work.



ns1 14400 IN A 69.1.2.3
ns2 14400 IN A 69.2.3.4

3.2.1.69.in-addr.arpa. 14400 IN PTR ns1.abcd.com.
4.3.2.69.in-addr.arpa. 14400 IN PTR ns2.abcd.com.


Also upstream provider has been set up.


Thanks

How do I check if my webhost provider has enabled reverse DNS on my server? Do we need to contact the webhost each time we add new domain (IP-based account) on the box to setup reverse DNS?
