# connectionWithRegisteredName:host:

Returns the `NSConnection` object whose send port links it to the `NSConnection` object registered with the default `NSPortNameServer` under a given name on a given host.

```
+ (instancetype) connectionWithRegisteredName:(NSString *) name host:(NSString *) hostName;
```

## Parameters

`name`

The name of an `NSConnection` object.

`hostName`

The name of the host. The domain name `hostName` is an Internet domain name (for example, “`sales.anycorp.com`”). If `hostName` is `nil` or empty, then only the local host is searched for the named `NSConnection` object.

## Return Value

The `NSConnection` object whose send port links it to the `NSConnection` object registered with the default `NSPortNameServer` under `name` on the host named `hostName`. Returns `nil` if no `NSConnection` object can be found for `name` and `hostName`. The returned `NSConnection` object is a child of the default `NSConnection` object for the current thread (that is, it shares the default `NSConnection` object’s receive port).

## Discussion

To get the object vended by the `NSConnection` object, use the [`rootProxy`](/documentation/Foundation/NSConnection/rootProxy) instance method. The [`rootProxyForConnectionWithRegisteredName:host:`](/documentation/Foundation/NSConnection/rootProxyForConnectionWithRegisteredName:host:) class method immediately returns this object.

## See Also

[`+ (NSConnection *) defaultConnection;`](/documentation/Foundation/NSConnection/defaultConnection)

Returns the default `NSConnection` object for the current thread.
