Question DNS: A and CNAME records don't work outside host

[Birgir Hrafn]

Hello

I am hosting several domains and subdomains and I want to point a subdomain to a domain that is not mine.
I'm provided with a Plesk Parallels. I have DNS settings that seem to work ONLY for domains that I am hosting within that provider.

Only the sd4.example.com and sd2.example.com don't work.
They are A and CNAME records that point to an external web-app.

Notice that sd3.example.com is a CNAME that does work, but it points to another domain that is using the same host/ip.

Note: Whatever subdomain I type, it does serve me with the "Web Server's Default Page".

Does anyone have any idea why A/CNAME records don't work outside the host?

Here is a screenshot of the settings:

Best regards

Hi Birgir Hrafn,

I suggest checking correct setting on registrar side that it points exactly to your server. Also, check that ip1-server correctly configured for serving requests for somedomain.com
