# Use DNS discovery to connect to existing nodes
|
||
|
|
|
||
|
|
> **Note:** This page describes using DNS to discover other peers
|
||
|
|
and is unrelated to the [domain name configuration](./configure-domain.md) for your go-waku node.
|
||
|
|
|
||
|
|
A node can discover other nodes to connect to using [DNS-based discovery](../../tutorial/dns-disc.md).
|
||
|
|
The following command line options are available:
|
||
|
|
|
||
|
|
```
|
||
|
|
--dns-discovery Enable DNS Discovery
|
||
|
|
--dns-discovery-url URL for DNS node list in format 'enrtree://<key>@<fqdn>'
|
||
|
|
--dns-discovery-name-server DNS name server IPs to query. Argument may be repeated.
|
||
|
|
```
|
||
|
|
|
||
|
|
- `--dns-discovery` is used to enable DNS discovery on the node.
|
||
|
|
Waku DNS discovery is disabled by default.
|
||
|
|
- `--dns-discovery-url` is mandatory if DNS discovery is enabled.
|
||
|
|
It contains the URL for the node list.
|
||
|
|
The URL must be in the format `enrtree://<key>@<fqdn>` where `<fqdn>` is the fully qualified domain name and `<key>` is the base32 encoding of the compressed 32-byte public key that signed the list at that location.
|
||
|
|
- `--dns-discovery-name-server` is optional and contains the IP(s) of the DNS name servers to query.
|
||
|
|
If left unspecified, the Cloudflare servers `1.1.1.1` and `1.0.0.1` will be used by default.
|
||
|
|
|
||
|
|
A node will attempt connection to all discovered nodes.
|
||
|
|
|
||
|
|
This can be used, for example, to connect to one of the existing fleets.
|
||
|
|
Current URLs for the published fleet lists:
|
||
|
|
- production fleet: `enrtree://ANTL4SLG2COUILKAPE7EF2BYNL2SHSHVCHLRD5J7ZJLN5R3PRJD2Y@prod.waku.nodes.status.im`
|
||
|
|
- test fleet: `enrtree://AOFTICU2XWDULNLZGRMQS4RIZPAZEHYMV4FYHAPW563HNRAOERP7C@test.waku.nodes.status.im`
|
||
|
