ServicePointManager.EnableDnsRoundRobin Property
.NET Framework (current version)
Gets or sets a value that indicates whether a Domain Name Service (DNS) resolution rotates among the applicable Internet Protocol (IP) addresses.
Assembly: System (in System.dll)
Property Value
Type: System.Booleanfalse 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.
ServicePointManager.UseNagleAlgorithm = true; ServicePointManager.Expect100Continue = true; ServicePointManager.CheckCertificateRevocationList = true; ServicePointManager.DefaultConnectionLimit = ServicePointManager.DefaultPersistentConnectionLimit; ServicePointManager.EnableDnsRoundRobin = true; ServicePointManager.DnsRefreshTimeout = 4*60*1000; // 4 minutes
