### A note about HTTPS
Before doing any of this, please note that modern browsers are set up to use
HTTPS, and so they validate the certificate of the web server they're trying to
reach for authenticity. That means that using any of these will result in
warning screens.
There are a couple of proposed extensions that, when they become reasonably well
supported by clients, would allow for a better user experience, including the
[RFC 8914 Extended DNS Error codes][rfc8914] and the [DNS Access Denied Error
Page RFC draft][rfcaccess]. We'll implement them when browsers actually start
to support them.
[rfc8914]: https://datatracker.ietf.org/doc/html/rfc8914
[rfcaccess]: https://datatracker.ietf.org/doc/html/draft-reddy-dnsop-error-page-08
### Prerequisites
To use any of these ways to show a custom block page, you'll need an HTTP server
running on some IP address and serving the page in question on all routes.
Something like [`pixelserv-tls`][pxsrv].

### Custom block page for parental control and safe browsing filters
There is currently no way to set these parameters from the UI, so you'll need to
edit the configuration file manually:
1. Stop AdGuard Home:
```sh
./AdGuardHome -s stop
```
1. Open `AdGuardHome.yaml` in your editor.
1. Set the `dns.parental_block_host` or `dns.safebrowsing_block_host` settings
to the IP address of the server (in this example, `192.168.123.45`):
```yaml
# …
dns:
# …
# NOTE: Change to the actual IP address of your server.
parental_block_host: 192.168.123.45
safebrowsing_block_host: 192.168.123.45
```
1. Restart AdGuard Home:
```sh
./AdGuardHome -s start
```
### Custom block page for other filters
1. Open the web UI.
1. Open the “Settings → DNS settings” page.
1. In the “DNS server configuration” section, select the “Custom IP” radio
button in the “Blocking mode” selector and enter the IPv4 and IPv6 addresses
of the server.
1. Click “Save”.

Here are some examples of what cannot be blocked by a DNS-level blocker:
* YouTube, Twitch ads.
* Facebook, Twitter, Instagram sponsored posts.
Essentially, any advertising that shares a domain with content cannot be blocked
