A virtual server without a pool member gives wrong answers for the records in the Wide IP list.

Hi everyone,   I created a virtual server on LTM to be able to answer dns request and I have not assigned any pool member for that virtual server. My aim is just to return answers for the records ...

Try Changing the DNS setting under your IPv4 adapter advanced settings , choose Append these DNS suffixes , and add dot (.) as a domain suffix .This should remove any extra suffix from your query.

Actually, just I wonder if no pool member exists for a listener, and the dns settings of a windows client machine is set as "Append primary and connection specific DNS suffixes" and "Append parent suffixes of the primary DNS suffix", why the query attempts of dns are not made till the top-level domain (i mean till dot (.)).

 

Please check the sample tcpdump output on the question to make it clear. Maybe it is not an important issue or it is specific to my settings, condition etc., if it does not make sense, you can just ignore it.

 

Thank you for your interest.
