Connect to 1.1.1.1 using DoH clients

There are several DoH clients you can use to connect to 1.1.1.1.

cloudflared

1. Download and install the cloudflared daemon.

2. Verify that the cloudflared daemon is installed by entering the following command:

   cloudflared --version

   cloudflared version 2020.11.11 (built 2020-11-25-1643 UTC)

3. Start the DNS proxy on an address and port in your network. If you do not specify an address and port, it will start listening on localhost:53. DNS (53) is a privileged port, so for the initial demo we will use a different port:

   cloudflared proxy-dns --port 5553

   INFO[2020-12-04T19:58:57Z] Adding DNS upstream - url: https://1.1.1.1/dns-query
   INFO[2020-12-04T19:58:57Z] Adding DNS upstream - url: https://1.0.0.1/dns-query
   INFO[2020-12-04T19:58:57Z] Starting metrics server on 127.0.0.1:44841/metrics
   INFO[2020-12-04T19:58:57Z] Starting DNS over HTTPS proxy server on: dns://localhost:5553

4. You can verify that cloudflared is running using a dig, kdig, host, or any other DNS client.

   dig +short @127.0.0.1 -p5553 cloudflare.com AAAA

   2606:4700::6810:85e5
   2606:4700::6810:84e5

5. Run cloudflared as a service so it starts on user login. On many Linux distributions, this can be done with:

   sudo tee /etc/systemd/system/cloudflared-proxy-dns.service >/dev/null <<EOF

   [Unit]
   Description=DNS over HTTPS (DoH) proxy client
   Wants=network-online.target nss-lookup.target
   Before=nss-lookup.target
   
   [Service]
   AmbientCapabilities=CAP_NET_BIND_SERVICE
   CapabilityBoundingSet=CAP_NET_BIND_SERVICE
   DynamicUser=yes
   ExecStart=/usr/local/bin/cloudflared proxy-dns
   
   [Install]
   WantedBy=multi-user.target
   EOF

   sudo systemctl enable --now cloudflared-proxy-dns

6. Change your system DNS servers to use 127.0.0.1. On Linux, you can modify /etc/resolv.conf:

   sudo rm -f /etc/resolv.conf
   echo nameserver 127.0.0.1 | sudo tee /etc/resolv.conf >/dev/null

7. Finally, verify it locally with:

   dig +short @127.0.0.1 cloudflare.com AAAA

   2606:4700::6810:85e5
   2606:4700::6810:84e5

DNSCrypt-Proxy

The DNSCrypt-Proxy ↗ 2.0+ supports DoH out of the box. It supports both 1.1.1.1 and other services. It also includes more advanced features, such as load balancing and local filtering.

1. Install DNSCrypt-Proxy ↗.

2. Verify that dnscrypt-proxy is installed and the version is 2.0 or later:

   dnscrypt-proxy -version

   2.0.8

3. Set up the configuration file using the official instructions ↗, and add cloudflare and cloudflare-ipv6 to the server list in dnscrypt-proxy.toml:

   server_names = ['cloudflare', 'cloudflare-ipv6']

4. Make sure that nothing else is running on localhost:53, and check that everything works as expected:

   dnscrypt-proxy -resolve cloudflare-dns.com

   Resolving [cloudflare-dns.com]
   
   Domain exists:  yes, 3 name servers found
