<strong>Network-wide ad blocking via your own Linux hardware</strong>
|
|
</p>
|
|
|
|
The Pi-hole[®](https://pi-hole.net/trademark-rules-and-brand-guidelines/) is a [DNS sinkhole](https://en.wikipedia.org/wiki/DNS_Sinkhole) that protects your devices from unwanted content, without installing any client-side software.
|
|
|
|
- **Easy-to-install**: our versatile installer walks you through the process, and [takes less than ten minutes](https://www.youtube.com/watch?v=vKWjx1AQYgs)
|
|
- **Resolute**: content is blocked in _non-browser locations_, such as ad-laden mobile apps and smart TVs
|
|
- **Responsive**: seamlessly speeds up the feel of everyday browsing by caching DNS queries
|
|
- **Lightweight**: runs smoothly with [minimal hardware and software requirements](https://discourse.pi-hole.net/t/hardware-software-requirements/273)
|
|
- **Robust**: a command line interface that is quality assured for interoperability
|
|
- **Insightful**: a beautiful responsive Web Interface dashboard to view and control your Pi-hole
|
|
- **Versatile**: can optionally function as a [DHCP server](https://discourse.pi-hole.net/t/how-do-i-use-pi-holes-built-in-dhcp-server-and-why-would-i-want-to/3026), ensuring *all* your devices are protected automatically
|
|
- **Scalable**: [capable of handling hundreds of millions of queries](https://pi-hole.net/2017/05/24/how-much-traffic-can-pi-hole-handle/) when installed on server-grade hardware
|
|
- **Modern**: blocks ads over both IPv4 and IPv6
|
|
- **Free**: open source software which helps ensure _you_ are the sole person in control of your privacy

|
## One-Step Automated Install
|
|
|
|
Those who want to get started quickly and conveniently may install Pi-hole using the following command:
|
|
|
|
```bash
|
|
curl -sSL https://install.pi-hole.net | bash
|
|
```
|
|
|
|
## Alternative Install Methods
|
|
|
|
[Piping to `bash` is controversial](https://pi-hole.net/2016/07/25/curling-and-piping-to-bash), as it prevents you from [reading code that is about to run](https://github.com/pi-hole/pi-hole/blob/master/automated%20install/basic-install.sh) on your system. Therefore, we provide these alternative installation methods which allow code review before installation:
|
|
|
|
### Method 1: Clone our repository and run
|
|
|
|
```bash
|
|
git clone --depth 1 https://github.com/pi-hole/pi-hole.git Pi-hole
|
|
cd "Pi-hole/automated install/"
|
|
sudo bash basic-install.sh
|
|
```
|
|
|
|
### Method 2: Manually download the installer and run
|
|
|
|
```bash
|
|
wget -O basic-install.sh https://install.pi-hole.net
|
|
sudo bash basic-install.sh
|
|
```
|
|
|
|
## Post-install: Make your network take advantage of Pi-hole
|
|
|
|
Once the installer has been run, you will need to [configure your router to have **DHCP clients use Pi-hole as their DNS server**](https://discourse.pi-hole.net/t/how-do-i-configure-my-devices-to-use-pi-hole-as-their-dns-server/245) which ensures that all devices connecting to your network will have content blocked without any further intervention.
|
|
|
|
If your router does not support setting the DNS server, you can [use Pi-hole's built-in DHCP server](https://discourse.pi-hole.net/t/how-do-i-use-pi-holes-built-in-dhcp-server-and-why-would-i-want-to/3026); just be sure to disable DHCP on your router first (if it has that feature available).
|
|
|
|
As a last resort, you can always manually set each device to use Pi-hole as their DNS server.

## Pi-hole is free, but powered by your support
|
|
|
|
There are many reoccurring costs involved with maintaining free, open source, and privacy-respecting software; expenses which [our volunteer developers](https://github.com/orgs/pi-hole/people) pitch in to cover out-of-pocket.

## Faster-than-light Engine
|
|
|
|
FTLDNS is a lightweight, purpose-built daemon used to provide statistics needed for the Web Interface, and its API can be easily integrated into your own projects. As the name implies, FTLDNS does this all *very quickly*!
|
|
|
|
Some of the statistics you can integrate include:
|
|
|
|
- Total number of domains being blocked
|
|
- Total number of DNS queries today
|
|
- Total number of ads blocked today
|
|
- Percentage of ads blocked
|
|
- Unique domains
|
|
- Queries forwarded (to your chosen upstream DNS server)
|
|
- Queries cached
|
|
- Unique clients
|
|
|
|
The API can be accessed via [`telnet`](https://github.com/pi-hole/FTL), the Web (`admin/api.php`) and Command Line (`pihole -c -j`). You can out find [more details over here](https://discourse.pi-hole.net/t/pi-hole-api/1863).

## The Origin Of Pi-hole
|
|
|
|
Pi-hole being an **advertising-aware DNS/Web server**, makes use of the following technologies:
|
|
|
|
- [`dnsmasq`](http://www.thekelleys.org.uk/dnsmasq/doc.html) - a lightweight DNS and DHCP server
|
|
- [`curl`](https://curl.haxx.se/) - A command line tool for transferring data with URL syntax
|
|
- [`lighttpd`](https://www.lighttpd.net/) - web server designed and optimized for high performance
|
|
- [`php`](https://www.php.net/) - a popular general-purpose web scripting language
|
|
- [AdminLTE Dashboard](https://github.com/ColorlibHQ/AdminLTE) - premium admin control panel based on Bootstrap 3.x
|
|
|
|
While quite outdated at this point, [this original blog post about Pi-hole](https://jacobsalmela.com/2015/06/16/block-millions-ads-network-wide-with-a-raspberry-pi-hole-2-0/) goes into **great detail** about how Pi-hole was originally set up and how it works. Syntactically, it's no longer accurate, but the same basic principles and logic still apply to Pi-hole's current state.
