# auberge dns set
Create or update a Cloudflare A record for a subdomain. Alias: `auberge d s`.
```bash
auberge dns set --subdomain <NAME> --ip <IP>
```
Upserts: updates the existing record if present, creates it otherwise. TTL is set to 1 (automatic). Record is DNS-only (not proxied).
## Options
| `-s, --subdomain NAME` | Subdomain name | Yes |
| `-i, --ip IP` | IPv4 or IPv6 address | Yes |
| `-P, --production` | Use production API | No |
## Examples
```bash
auberge dns set --subdomain freshrss --ip 192.168.1.10
auberge dns set --subdomain baikal --ip 10.0.0.5 --production
```
## Gotchas
- Invalid IP formats are rejected immediately.
- Cloudflare updates are instant but recursive resolvers may cache for up to the TTL. Verify with `dig freshrss.example.com`.
- For multiple subdomains use `auberge dns set-all --host myserver`.
