+- `HOSTNAMEFQDN` serve the machine's global hostname as fully qualified domain by adding the local suffix. See note below.
 - `NONE` Pi-hole will **not** respond automatically on PTR requests to local interface addresses. Ensure `pi.hole` and/or hostname records exist elsewhere.
 
+Note about `HOSTNAMEFQDN`: If no local suffix has been defined, FTL appends the local domain `.no_fqdn_available`. In this case you should either add `domain=whatever.com` to a custom config file inside `/etc/dnsmasq.d/` (to set `whatever.com` as local domain) or use `domain=#` which will try to derive the local domain from `/etc/resolv.conf` (or whatever is set with `resolv-file`, when multiple `search` directives exist, the first one is used).

 #### `DELAY_STARTUP=0` (PR [#716](https://github.com/pi-hole/FTL/pull/716)) {#delay_startup data-toc-label='Delay resolver startup'}
 
 In certain configurations, you may want FTL to wait a given amount of time before trying to start the DNS revolver. This is typically found when network interfaces appear only late during system startup and the interface startup priorities are configured incorrectly. This setting takes any integer value between 0 and 300 seconds.
