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 -resolve cloudflare-dns.com
