<p>These options are dangerous on devices
directly connected to the Internet such as cloud instances and are only safe if your
Pi-hole is properly firewalled. In a typical at-home setup where your Pi-hole is
located within your local network (and you have <strong>not</strong> forwarded port 53
in your router!) they are safe to use.</p>

<p>When there is a Pi-hole domain set and this box is
ticked, this asks FTL that this domain is purely
local and FTL may answer queries from <code>/etc/hosts</code> or DHCP leases
but should never forward queries on that domain to any upstream servers.
If Conditional Forwarding is enabled, unticking this box may cause a partial
DNS loop under certain circumstances (e.g. if a client would send TLD DNSSEC queries).</p>

<label for="DNSbogusPriv"><strong>Never forward reverse lookups for private IP ranges</strong></label>
<p>All reverse lookups for private IP ranges (i.e., <code>192.168.0.x/24</code>, etc.)
which are not found in <code>/etc/hosts</code> or the DHCP leases are answered
with "no such domain" rather than being forwarded upstream. The set
of prefixes affected is the list given in <a href="https://tools.ietf.org/html/rfc6303">RFC6303</a>.</p>
<p><strong>Important</strong>: Enabling these two options may increase your privacy,
but may also prevent you from being able to access
local hostnames if the Pi-hole is not used as DHCP server.</p>

<input type="checkbox" name="DNSSEC" id="DNSSEC" <?php if ($DNSSEC){ ?>checked<?php } ?>>
<label for="DNSSEC"><strong>Use DNSSEC</strong></label>
<p>Validate DNS replies and cache DNSSEC data. When forwarding DNS
queries, Pi-hole requests the DNSSEC records needed to validate
the replies. If a domain fails validation or the upstream does not
support DNSSEC, this setting can cause issues resolving domains.
Use an upstream DNS server which supports DNSSEC when activating DNSSEC. Note that
the size of your log might increase significantly
when enabling DNSSEC. A DNSSEC resolver test can be found
<a href="https://dnssec.vs.uni-due.de/" rel="noopener" target="_blank">here</a>.</p>

<h4><a id="ratelimit"></a>Rate-limiting</h4>
<p>Block clients making more than <input type="number" name="rate_limit_count" value="<?=$rate_limit_count?>" min="0" step="10" style="width: 5em;"> queries within
<input type="number" name="rate_limit_interval" value="<?=$rate_limit_interval?>" min="0" step="10" style="width: 4em;"> seconds.</p>
<p>When a client makes too many queries in too short time, it
gets rate-limited. Rate-limited queries are answered with a
<code>REFUSED</code> reply and not further processed by FTL
and prevent Pi-holes getting overwhelmed by rogue clients.
It is important to note that rate-limiting is happening on a
per-client basis. Other clients can continue to use FTL while
rate-limited clients are short-circuited at the same time.</p>
<p>Rate-limiting may be disabled altogether by setting both
values to zero. See
<a href="https://docs.pi-hole.net/ftldns/configfile/#rate_limit" target="_blank">our documentation</a>
for further details.</p>

<h4>Conditional forwarding</h4>
<p>If not configured as your DHCP server, Pi-hole typically won't be able to
determine the names of devices on your local network. As a
result, tables such as Top Clients will only show IP addresses.</p>
<p>One solution for this is to configure Pi-hole to forward these
requests to your DHCP server (most likely your router), but only for devices on your
home network. To configure this we will need to know the IP
address of your DHCP server and which addresses belong to your local network.
Exemplary input is given below as placeholder in the text boxes (if empty).</p>
<p>If your local network spans 192.168.0.1 - 192.168.0.255, then you will have to input
<code>192.168.0.0/24</code>. If your local network is 192.168.47.1 - 192.168.47.255, it will
be <code>192.168.47.0/24</code> and similar. If your network is larger, the CIDR has to be
different, for instance a range of 10.8.0.1 - 10.8.255.255 results in <code>10.8.0.0/16</code>,
whereas an even wider network of 10.0.0.1 - 10.255.255.255 results in <code>10.0.0.0/8</code>.
Setting up IPv6 ranges is exactly similar to setting up IPv4 here and fully supported.
Feel free to reach out to us on our
<a href="https://discourse.pi-hole.net" rel="noopener" target="_blank">Discourse forum</a>
in case you need any assistance setting up local host name resolution for your particular system.</p>
<p>You can also specify a local domain name (like <code>fritz.box</code>) to ensure queries to
devices ending in your local domain name will not leave your network, however, this is optional.
The local domain name must match the domain name specified
in your DHCP server for this to work. You can likely find it within the DHCP settings.</p>
<p>Enabling Conditional Forwarding will also forward all hostnames (i.e., non-FQDNs) to the router
when "Never forward non-FQDNs" is <em>not</em> enabled.</p>
