# DNSCrypt Proxy 2 for Android
A flexible DNS proxy, with support for modern encrypted DNS protocols such as [DNSCrypt v2](https://github.com/DNSCrypt/dnscrypt-protocol/blob/master/DNSCRYPT-V2-PROTOCOL.txt) and [DNS-over-HTTP/2](https://tools.ietf.org/html/draft-ietf-doh-dns-over-https-03).
## Features
- arm, arm64, x86 and x86_64 are supported.
- ipv4 and ipv6 are supported.
- All binary files are downloaded from [https://github.com/jedisct1/dnscrypt-proxy/releases](https://github.com/jedisct1/dnscrypt-proxy/releases)
## Installation
- Download [.zip module](https://github.com/Magisk-Modules-Repo/dnscrypt-proxy-magisk/releases), flash it in Magisk Manager App or in Recovery and follow the instructions.
- There are two option in installation progress.
### Auto redirect DNS queries using `iptables`
Just flash and forget.
### Set DNS server manually with 3rd-party app (not included in this module)
- DNS server address is 127.0.0.1:53 for ipv4 and [::1]:53 for ipv6
- If you use AfWall, you can write this enter custom script
```
iptables -t nat -A OUTPUT -p tcp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination 127.0.0.1:53
iptables -t nat -A OUTPUT -p udp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination 127.0.0.1:53
ip6tables -t nat -A OUTPUT -p tcp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination [::1]:53
ip6tables -t nat -A OUTPUT -p udp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination [::1]:53
```
and this shutdown script
```
iptables -t nat -D OUTPUT -p tcp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination 127.0.0.1:53
iptables -t nat -D OUTPUT -p udp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination 127.0.0.1:53
ip6tables -t nat -D OUTPUT -p tcp ! -d 9.9.9.9 --dport 53 -j DNAT --to-destination [::1]:53
