- :func:`setRandomizedIdsOverUDP` will randomize the IDs in outgoing queries, at a small performance cost. :func:`setMaxUDPOutstanding`
should be set at its highest possible value (default since 1.4.0) to make that setting fully efficient.

- :func:`setRandomizedOutgoingSockets` can be used to randomize the outgoing socket used when forwarding a query to a backend.
This requires configuring the backend to use more than one outgoing socket via the ``sockets`` parameter of :func:`newServer`
to be of any use.
