--- title: Overview of Pi-hole description: Brief overview of Pi-hole ---
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 - **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](main/prerequisites.md) - **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 --- ## 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. This is just one example of how strongly we feel about our software, as well as the importance of keeping it maintained.
