I have a question of understanding about the cache in Pi-hole.
I have Pi-hole v5.2.4 | Web Interface v5.4 | FTL v5.7 installed, with a local Unbound 1.13.1 as upstream DNS server.
Pi-hole is running with
Unbound is running with
My expectation is, every entry in the Pi-hole cache has a TTL of 900 seconds (15 minutes) or more.
9 minutes after a restart with
pihole restartdns the web interface shows:
DNS cache size: 300 DNS cache insertions: 372 DNS cache evictions: 0
After the above mentioned 9 minutes the oldest entries in the cache should still have a TTL of approx. 6 minutes = cache is full. Why there are 0 evictions?
