Pinging a subdomain gets reply from a foreign IP. Accessing the subdomain loads a ngix default page, I have no such server installed.
This behavior is only at a single domain and single subdomain.
Once the subdomain existed, and was used.
There is no DNS record for this subdomain. Tried to create, but does not affect. It is uncontrollable.
I have created old.knorimpex.ro and cold.knorimpex.ro both A records, pointing to the same IPv4 address. cold.knorimpex.ro or any other except old runs fine, old lands on a ngix server. I do not have such server installed. I do not have any control on old.knorimpex.ro
Bitdefender says that is a “Suspicious page”.
How can I fix it?
