DNS - Subdomain forwarding

[Frank Hagan]

I have a domain I'm using for a domain name reseller account. I can point the "http://www.mydomain.tld" domain to the reseller account by using a CNAME record, and configure their control panel to accept it:

www.mydomain.tld IN CNAME www.otherdomain.tld

Works like a champ ... when you type "www.mydomain.tld" in the browser, up comes the site at "www.otherdomain.tld".

They also give me an IP address to use for a sub-domain used for sub-resellers who sign up under me:

reseller.mydomain.tld IN A 0.0.0.126

This also works great ... type in "reseller.mydomain.tld" and up comes the "reseller.otherdomain.tld" site.

There are also two additional URLs used for accessing the control panels to manage the domain names, one for customers and sub-resellers. I would like to have a sub-domain point to them, but I only have the URL, not the IP address. So:

customer.mydomain.tld IN A www.otherdomain.tld/customer

Does not work ... so I suspect A records always require an IP address. WHM will accept it as a CNAME entry, but I'm not sure if that will work. Anyone have any ideas on this one?

You cannot do that using DNS. DNS works only on IP addresses and domains, not URL's.
It would work if they set www.otherdomain.tld/customer to be accessible as customer.otherdomain.tld and then you set

customer.mydomain.tld IN CNAME customer.otherdomain.tld

[Frank Hagan]

Thanks, Pedja. They did respond and say that I could use CNAME records to point to it, but I'm unsure if this format would work:

customer.mydomain.tld IN CNAME www.otherdomain.tld/customer

Or if I should stick with:

www.mydomain.tld/customer IN CNAME www.otherdomain.tld/customer

Guess I'll try it and see!

You cannot use www.otherdomain.tld/customer at all. HTTP URLs like that will not work, only valid domains and subdomains can be used.

[Frank Hagan]

Thanks, Andrew! I think you saved me a few hours of frustration!

I'll get back to them and find out what the valid URL is for the "customer control panel" login on their site.

Well ... round two ....

They have given me an IP address, but it doesn't seem to be resolving. I created two A records Friday:

manage.MyDomainName.tld. IN A 67.15.47.4
controlpanel.MyDomainName.tld IN A 67.15.47.4

When I try to surf to the domains above, the browser gives me the default search engine page (Google, in my case) with the error message that "Your search ... did not match any documents".

I can ping the IP address OK, but if I put it into a browser's address bar, I get an error from their system.

I'm thinking If they didn't configure their system to look for my subdomains on that IP address, I might get that browser error. Or, if the DNS records are not being updated from my server here at Dathorn, then I might get that error (but I'm betting the problem is on their end!) Any advice?

[AndrewT]

As always, submit a trouble ticket and we can take a look at it.

[Frank Hagan]

Just did ... didn't want to do it prematurely, as it usually isn't Dathorn's issue! I think of all the trouble tickets I've submitted, about 99% have been either on my end or somewhere else "out there".

How are you editing the DNS entries? I thought I had done it in the past, but don't see anything in WHM or cpanel to modify A or CNAME records.

Submit a ticket and let us know what you would like added or modified.
