Even # when fragmentation does work, it may not be secure; it is theoretically # possible to spoof parts of a fragmented DNS message, without easy # detection at the receiving end. Recently, there was an excellent study # >>> Defragmenting DNS - Determining the optimal maximum UDP response size for DNS <<< # by Axel Koolhaas, and Tjeerd Slokker (https://indico.dns-oarc.net/event/36/contributions/776/) # in collaboration with NLnet Labs explored DNS using real world data from the # the RIPE Atlas probes and the researchers suggested different values for # IPv4 and IPv6 and in different scenarios. They advise that servers should # be configured to limit DNS messages sent over UDP to a size that will not # trigger fragmentation on typical network links. DNS servers can switch # from UDP to TCP when a DNS response is too big to fit in this limited # buffer size. This value has also been suggested in DNS Flag Day 2020. edns-buffer-size: 1232 # Perform prefetching of close to expired message cache entries # This only applies to domains that have been frequently queried prefetch: yes # One thread should be sufficient, can be increased on beefy machines.

dig pi-hole.net @127.0.0.1 -p 5335
Konfiguriere zu SchlussPi-hole so, dass es deinen rekursiven DNS-Server verwendet, indem Du folgende benutzerdefinierte DNS angibst.
Der erste Befehl sollte einen Statusbericht von SERVFAIL und keine IP-Adresse liefern. Der zweite sollte NOERROR plus eine IP-Adresse ausgeben.
