Apparatus for operating as a server node within a private IP network to host or aggregate a plurality of resources. The apparatus comprises an address controller for obtaining a private IP network IP address, for allocating a server node port number to said resources, and for causing the server node to listen on that server node port. A resource configurator is provided for determining for each of said resources a resource private Uniform Resource Identifier, URI, or URI path together with resource metadata, and for sending to a gateway, interconnecting the private IP network with a public IP network, an advertisement containing said private URI or URI path and respective resource metadata. The apparatus further comprises a resource request receiver for receiving requests at said server node port, for identifying private URIs or URI paths included within the requests, and for delivering resources corresponding to said URI or URI paths.
