Explanation of subdomain and domain pointing

Hello,

I had my domain name registered at place A. Now I transfered the domain name to place B. This was 10 days ago and at place B I dont have a homepage, at place A I still have the homepage hosted. When I try to access my domain I still see my old homepage. Why is this?

I also have a webserver at place B. I registered a subdomain at place B and want to point that subdomain to the webserver. I used place B web interface and added my subdomain and pointed it to the external IP address of the webserver. This doesnt work and when I contact place B and asks about this, they say you need to configure the DNS on the webserver but I cant see why this is necessary at all. I mean when you try to access a homepage you are directed to the domain name's host and then pointed wherever the IP you supplied. Has nothing to do with the server you are pointing towards, right? If this theory is incorrect please enlighten me.

Ok so the question really is what do I do to point a webhosted subdomain name to an external IP?

Regards
Robert

This is how DNS works:

1) you register the domain name with a registrar
2) you provide the DNS servers for your domain in the registration process
3) you update the authoritative name servers to be authoritative for that domain
4) you create a 'www' record (or whatever) that points to the IP address of the webserver

If you gave us a real domain name and the new hosting provider, we could better trouble shoot the issue

For your first question, try going to http://www.kloth.net/services/nslookup.php and look up the name of your site. It will give you the IP address. If it gives you the old address, then you know that the transfer is not complete. Even if the domain name was moved, you also need to tell the new ISP to change the DNS entry for whatever you're accessing.

2nd question: I am wondering if NAT is configured correctly on your router. You mention external IP address, so that means that you are doing NAT. Check the NAT config and make whatever changes are required for the new IP address.

Hello,

Thanks for your answers, the old hosting provider was dispono.net and the new one is space2u.com. So should I tell space2u.com or Bredbandsbolaget to change their DNS? About the external IP and NAT, thats configured correctly because when I surf to the IP I hit the webserver.

Typically when you change your authoritative servers, you request your old DNS/Web provider to cease providing these services.

What is your domain name?

I show the authoritative name servers for your domain are:

ns.ibase.st
ns2.ibase.st

Both servers report www.ilexconsulting.se with an A record of: 213.136.36.35

This is in the dispono address space.

When I dig against space2u.com's name servers, they do respond with an A record for your webserver.

If you can verify that your web site pulls up properly at space2.com, then you need to change the authoritative nameservers at your registrar from ibase.st to the nameservers that space2u provided for you.
