Make sure you have registered the nameservers at the registrar, also if you post your domain here others could probably help you to see whats going wrong

Right, i have changed my DNS records for www and @ to my IP. I have also used WHM on my server to change the hostname to mydomain.com persay and the nameservers to ns1.mydomain.com and ns2.mydomain.com but my domain has not resolved yet and it has been more than 24 hours, any idea why this is?

The reverse DNS is simply for those who run mail servers, and need their IP to resolve back to their domain name. Its an anti-spam measure used by e-mail servers to verify the e-mail didn't come from a spoof address. Its not required but it can help.

You simply set the reverse DNS to your domain name. It won't have any impact on your website working or not.

the @ simply means that http://domain.com points to your servers IP, and www means that http://www.domain.com points to your servers IP too. "A" is the type of entry. most companies that host domains should let you change these things. Then, i believe OVH let you change the Reverse DNS, so for that you'd enter in domain.com.

its important to note the fullstop at the end of the domain, domain.com. that has to be there thats a basic overview of how to do it
Thanks for a prompt and informative response.

I have change my DNS records to point to my new IP. I did this last night, as i believed that was what i had to do.

"Then, i believe OVH let you change the Reverse DNS, so for that you'd enter in domain.com."

Can you clarify this for me? I am unsure about what you mean.

Also, if i don't change my hostname to my new domain does this mean my new domain will not resolve properly?

Hi folks,

I understand most concepts when it comes to servers, but i am unclear as to the full functionality of DNS and more so how to get it sorted.

At the moment, my hostname is *****.kimsufi.com (* = number)

Now if i was to change that to: mydomain.com

I would obviously have to change informations in the registrars entries in order to get it to do that, but what information would i change? Nemservers? DNS? MX records?

Could somebody help me as to what needs doing in order for me to be able to change the host name and have mydomain.com to point to my server?

Thanks!
