I removed all additional entries for my clients from the hosts file to the custom.list file. So I am able to edit them in the pi-hole webui under „DNS Records“.
Now all client names are still resolved in the statistics - that was easy and looks as usual. But NOT in the long-term database statistics, only the IPs are shown here!
::1 localhost ip6-localhost ip6-loopback
I am ussing the router for DHCP.
Did I miss something, are there additional steps to do?
