ResolutionThis can be caused by the following configuration:
For example, the /etc/resolv.conf file has a record like "search somedomain.com".
And the DNS server has a record like "*.somedomain.com A SERVER_IP".
In this case if you try to resolve any name (for example somedomain1.com) and it is not resolved, nameserver tries to
find new-domain.com.somedomain.com, but all *.somedomain.com domains are resolved. That is why the warning may arise.
