SlowDNS proxies DNS over UDP, with two configurable block levels.
- Hard: Domains resolve to
0.0.0.0, a la pi-hole. - Soft: After a 30 second delay, the domains resolve normally.
Hard blocking is useful to block trackers, ads, and other bloat.
Soft blocking is useful to retrain learned browsing habits for instant gratification.
The server can be built and run with
go install github.com/spencer-p/slowdns
export PORT=53 DNSSERVERS=8.8.8.8

make docker-run

I built this as a means to an end. It is not high quality and you should not depend on it.
- Not RFC compliant. My reference was Wireshark packet dumps.
- Potentially not your-home-network compliant.
- Reddit, Hacker News, and Instagram are hardcoded to soft block.
