RandomDNS aims to improve the security, privacy and anonymity of DNSCrypt. It can randomize the server choice at runtime and can rotate it frequently.
DNSCrypt is a protocol that authenticates communications between a DNS client and a DNS resolver. It prevents DNS spoofing. It uses cryptographic signatures to verify that responses originate from the chosen DNS resolver and haven't been tampered with.

- Randomize the provider at runtime
- Use (-E)phemeral keys option
- Securely run DNSCrypt proxy by verifying its hash, copying it in /tmp dir with restricted permissions and launching it as "nobody" user (if reverse proxy is enabled)
- Watch the proxy process and relaunch it if it dies
- Can run multiple instances of DNSCrypt and load balance the traffic (EdgeDNS)
- Have in-memory caching of DNS requests along with Consistent Hashing (EdgeDNS)
- Can filter the server list by protocols, country and much more
- Rotate the server with a defined time (default: 10 minutes)
- Support DNSSEC (EdgeDNS)
- Update Brew:
brew update && brew upgrade
- Install DNSCrypt + Node + NPM:
brew install dnscrypt-proxy node npm
- Download and run RandomDNS:
npm install -g randomdns && sudo DEBUG=* randomdns
- Set your DNS settings to 127.0.0.1
