Pi-hole is very lightweight as it only handles DNS queries and returns a blank HTML file so it doesn't need much processing power.
- ~52MB of free space
- 512 MB RAM
Pi-hole will run on most Debian-based distro's and is the preferred platform for it.
We officially support the following:
- Raspbian: Jessie (lite / with pixel)
- Ubuntu: 14.04 / 16.04 / 16.10
- Fedora: 24 / 25
- Debian: 8.6
- CentOS: 7.2.1511 / 7.3.1611
We need port 53 for DNS and 80 for the Web server. However, the Web server port can be modified to a non-standard one if needed.
