This is what breaks recursive name resolvers like nip.io and sslip.io.

Meanwhile, the option is to disable Filter Private Rebind and wait to be hacked :fearful:

Changes here require changes in unbound startup modules to be effective. Search for the option there. Once you've added an option for $UB_TXT_DOMAIN then you can implement something in the GUI.

Is this getting better on v24? or is it still present?
