=> and it seems it is not very applied (e.g., my home ISP doesn't support DNS over TCP), perhaps because of [5966/5966bis]: Whilst this document makes no specific recommendations to operators of DNS servers, it should be noted that failure to support TCP (or the blocking of DNS over TCP at the network layer) may result in resolution failure and/or application-level timeouts. => so IMHO there are still things to do, even in the 5966bis intro...
