public static ServerName valueOf(final Address address, final long startCode) {

Retrieve an instance of {@link ServerName}. Callers should use the {@link #equals(Object)}
method to compare returned instances, though we may return a shared immutable object as an
internal optimization.
@param address   the {@link Address} to use for getting the {@link ServerName}
@param startCode the startcode to use for getting the {@link ServerName}
@return the constructed {@link ServerName}
