# Reverse DNS server for Fritzbox
This is a DNS server which fetches periodically network device information (Device name and IPv4+IPv6 addresses) from the Fritzbox web ui and provides device name for reverse DNS (PTR) queries. Works for IPv4 and IPv6 addresses. This tool can be configured als rDNS lookup in [blocky](https://github.com/0xERR0R/blocky) or AdguardHome.
## How to install
You can start this server as docker container with following `docker-compose.yaml` file
```yaml
version: "2.1"
services:
fritzbox-rdns:
container_name: fritzbox-rdns
image: ghcr.io/0xerr0r/fritzbox-rdns:latest
restart: unless-stopped
environment:
- "FB_URL=http://192.168.178.1"
- "FB_USER=username"
- "FB_PASSWORD=passw0rd"
- "FB_REDIS=redis:6379"
- "FB_LOG_LEVEL=info"
ports:
- "53:53/udp"
redis:
image: redis
restart: unless-stopped
command: redis-server --save 120 1 --loglevel warning
volumes:
- redis_data:/data

```
