Operates identically to {@code getByName} except host resolution is
performed on the network designated by {@code netId}.

@param host
the hostName to be resolved to an address or {@code null}.
@param netId the network to use for host resolution.
@return the {@code InetAddress} instance representing the host.
@throws UnknownHostException if the address lookup fails.
