 YARP uses a destination resolver to expand the set of configured destination addresses. The destination resolver can be used as an integration point with service discovery systems.
 
 ## Structure
-[IDestinationResolver](xref:Yarp.ReverseProxy.ServiceDiscovery.IDestinationResolver) has a single method `ResolveDestinationsAsync(IReadOnlyDictionary<string, DestinationConfig> destinations, CancellationToken cancellationToken)` which should return a [DestinationConfig](xref:Yarp.ReverseProxy.ServiceDiscovery.ResolvedDestinationCollection) instance. The [ResolvedDestinationCollection](xref:Yarp.ReverseProxy.ServiceDiscovery.ResolvedDestinationCollection) has a collection of [DestinationConfig](xref:Yarp.ReverseProxy.Configuration.DestinationConfig) instances, as well as an `IChangeToken` to notify the proxy when this information is out of date and should be reloaded, which will cause `ResolveDestinationsAsync` to be called again.

 ### DestinationConfig
 `DestinationConfig` has a `Host` property which can be used to specify the default `Host` header value which the proxy should use when communicating with that destination. This allows the `IDestinationResolver` to resolve destinations to a collection of IP addresses, for example, without causing SNI or host-based routing to fail.
