Hello, our stupid new host cannot help with following fatal bug:
Lets suppose we have domain.com hosted with them. We create many subdomains as subdomain1.domain.com, subdomain2.domain.com, subdomain3. domain.com,... etc
But their name server is able only to return correct IP for domain.com +
www.domain.com + just one subdomain. Other subdomains return domain does not exist. Funny thing is that the one subdomain resolved well is that one which is asked first from internet from last name server reset. So one day you can access subdomain3.domain.com and no other subdomain, next day is subdomain3.domain.com unavailable but you get subdomain6.domain.com, if next morning i start testing with subdomain2.domain.com there is this one happy for that day etc. :-)
The host is incredible stupid and they cannot find the error. I did never configure name server. But the symptoms look quite clear. Is there any guru who can guess what is wrong and how exactly fix this bug?
Domain plus all subdomains are configured to same IP address at same virtual account and they work properly. Problem is that name server does not return IP address for other subdomain than first happy one.
