Nameservers

Post by s.dot »

Ok, I have a question about name servers.

I am using cPanel on my server and it has the option to choose your server hostname, primary nameserver name, and secondary nameserver name.

I chose these values

Server Hostname: ns1.showmypro.com
Primary Nameserver: ns1.showmypro.com
Secondary Nameserver: ns2.showmypro.com

showmypro.com is a registered domain name.

My question is.. if I log in to my cpanel for my domain name, and point my DNS to ns1.showmypro.com and ns2.showmypro.com... it will work?

I would try it, but I don't want to waste up to 72 hours waiting for DNS to propagate in case of a mistake.

Your best bet is to use your registrar's nameservers, log into your registrar and edit your A record so it reflects the IP address of your machine, in the case you have 2 IPs (which you almost certainly do) you would set the primary A record to your primary IP and secondary respectively. You can check DNS records instantly (without waiting 72 hours) using the tools at http://www.dnsstuff.com/ and also visiting your website through multiple proxies can help, after a few tries you're sure to find a proxy that doesn't have the old DNS entry cached.

I went to that website and wasn't able to see the updated info. So maybe it's not instant?

My registrar won't let me input IP addresses.

Code: Select all

Note that these results are obtained in real-time, meaning that these are not cached results.
These results are what DNS resolvers all over the world will see right now (unless they have cached information).
Yes, it is instant, unless your registrar hasn't posted your updated DNS info that is. Regardless that tool shows exactly what the root nameservers show. If your registrar does not host nameservers, I recommend first off changing registrars as most quality registrars do. Or you need to download, compile/install and configure bind, personally I would transfer away from that registrar

If you are going to experiment with this, i suggest you:

- First delegate a subdomain to a different server, and then try things out with the settings for that subdomain
- Lower the TTL (Time To Live) of the dns records..
