Cloudflare Error 1000: DNS points to prohibited IP
A proxied DNS record points at a Cloudflare IP address, creating a loop.
Seen on:
Cloudflare
Meaning
Happens when you put a Cloudflare IP (from a previous proxied setup or a copy of the resolved address) into an A record, or when the origin is another Cloudflare-proxied site’s IP.
Common causes
- A record set to a Cloudflare anycast IP
- Origin is another Cloudflare-proxied hostname’s IP
- Reverse proxy on the origin forwarding back to the same domain
⚡ Quick fix
- Set the A record to your origin server’s real IP
- Use a CNAME to the origin hostname if it’s another service
- Check the origin’s proxy config for loops
Detailed fix by platform
Shell
- bash
# your server's real public IP (run on the origin) curl -s https://ifconfig.me
How to diagnose
- Record — IP in Cloudflare DNS
- Ownership — Is it a Cloudflare IP (104.16.0.0/13, 172.64.0.0/13…)?
