Explanation

Configuring Subnet Prioritization If the resolver receives multiple A resource records from a DNS server, and some have IP addresses from networks to which the computer is directly connected to, the resolver orders those resource records first. This reduces network traffic across subnets by forcing computers to connect to network resources that are closer to them. Subnet prioritization prevents the resolver from using the round robin feature, defined in RFC 1794. Using the round robin feature, the server rotates the order of resource record data returned in a query answer in which multiple resource records of the same type exist for a queried DNS You can also change the round robin setting from the registry; however, do so from the DNS snap-in instead. If Enable round robin is selected (the default) and the value of LocalNetPriority is 1, the server rotates among the A resource records that it returns in the order of their similarity to the IP address of the querying client. If Enable round robin is deselected and the value of LocalNetPriority is 1, the server returns the records in local net priority order. It does not rotate among available addresses. round-robin.aspx
