-\fBNAMES_FROM_NETDB=true|false\fR
-.br
-    Control whether FTL should use a fallback option and try to obtain client names from checking the network table.
-.br
-    E.g. IPv6 clients without a hostname will be compared via MAC address to known clients.
-.br
-
-\fB\fBREFRESH_HOSTNAMES=IPV4|ALL|NONE\fR
-.br
-    Change how (and if) hourly PTR requests are made to check for changes in client and upstream server hostnames:
-.br
-    IPV4 - Do the hourly PTR lookups only for IPv4 addresses resolving issues in networks with many short-lived PE IPv6 addresses.
-.br
-    ALL  - Do the hourly PTR lookups for all addresses. This can create a lot of PTR queries in networks with many IPv6 addresses.

-.br
-
-\fBMAXNETAGE=365\fR
-.br
-    IP addresses (and associated host names) older than the specified number of days are removed.

-.br
-
-\fBDBINTERVAL=1.0\fR
-.br
-    How often do we store queries in FTL's database [minutes]?
-.br
-    Accepts value between 0.1 (6 sec) and 1440 (1 day)
-.br
-
-\fBDBFILE=/etc/pihole/pihole-FTL.db\fR
-.br
-    Specify path and filename of FTL's SQLite long-term database.
