+
+Specifies custom DNS resolver addresses for `cloudflared` to use. Each address must be in `ip:port` format — providing an IP address without a port will cause `cloudflared` to fail to start. You can specify multiple resolvers by repeating the flag.
+
+A maximum of 10 resolver addresses are allowed.
+
+```sh
+cloudflared tunnel run --dns-resolver-addrs 1.1.1.1:53 <UUID or NAME>
+```
+
+To use multiple resolvers:
+
+```sh
+cloudflared tunnel run --dns-resolver-addrs 1.1.1.1:53 --dns-resolver-addrs 1.0.0.1:53 <UUID or NAME>
+```
