IP ???, ?? ?????? ??? ????? ??? ??? microsoft.com ??? When the DNS server receives a query for uk.sales.microsoft.com, it compares that domain name with both microsoft.com and example.microsoft.com. Both microsoft.com and sales.microsoft.com are contained in the query, but sales.microsoft.com is longer and the query is forwarded to the 10.10.10.100 IP address, which is associated with sales.microsoft.com.
• You can disable recursion for the DNS server so that it does not use recursion on any query. If you disable recursion on the DNS server, you cannot use forwarders on the same server.
