How can I disable DNS ADDITIONAL SECTION?

Thu Jan 07, 2021 6:28 am

Hi!
I am using DNS cache server in RouterOS.
I wanna know is there any option settings like restrict-authority-section-on-bind.
The default udp max size is 4096, and almost all of the queries bigger than 512 with ADDITIONAL SECTION. cause my internal application issue with DNS UDP larger than 512 oct.

I know the max-udp-packet-size setting make sense, but it transform all queries into TCP.
