I use DoH server and set Cache Size 2048 KB. Cache MAX TTL = 1 day. DNS work Ok.
After reboot and 1 day of work size of Cache Used = 2048 KB. Flush Cache not change size of Cache Used and remain 2048 KB. View table of DNS Cache show about 154 records and sometime change to 80 records (only static record). Where is Cache DNS ? 154 string - it is all Cache size 2048 KB ? What must I do ?
