ServicePointManager.EnableDnsRoundRobin Property

Gets or sets a value that indicates whether a Domain Name Service (DNS) resolution rotates among the applicable Internet Protocol (IP) addresses.

Namespace:  System.Net
Assembly:  System (in System.dll)

static member EnableDnsRoundRobin : bool with get, set

Property Value

Type: System.Boolean
false if a DNS resolution always returns the first IP address for a particular host; otherwise true. The default is false.

When more than one IP address is associated with a host name, a DNS resolution normally returns only the first IP address. If you set this property to true, then subsequent DNS resolutions will cycle through all available IP addresses for a particular host. This option is useful when a service uses DNS as a load balancing mechanism between servers or server clusters.

The following code example sets this property.
