public static ISiloBuilder ConfigureEndpoints(this ISiloBuilder builder, string? hostname, int siloPort, int gatewayPort, AddressFamily addressFamily = AddressFamily.InterNetwork, bool listenOnAnyHostAddress = false)
```

Configure endpoints for the silo.

### Parameters

- `builder` (`ISiloBuilder`): The host builder to configure.
- `hostname` (`string?`): The host name the silo is running on.
- `siloPort` (`int`): The port this silo uses for silo-to-silo communication.
- `gatewayPort` (`int`): The port this silo uses for client-to-silo (gateway) communication. Specify 0 to disable gateway functionality.
- `addressFamily` (`AddressFamily`): Address family to listen on. Default IPv4 address family.
- `listenOnAnyHostAddress` (`bool`): Set to true to listen on all IP addresses of the host instead of just the advertiseIP.
