Cfx Blacklist Checker
Cfx.re blocks some IPs and hosting ranges from running public servers. Paste IPs, host names or cfx.re join codes (up to 20 at once) and see which ones are blacklisted, straight from Cfx's own endpoint.
Paste the IP of a VPS or dedicated server before you rent it, or a join code to check a running server.
What the result means
- Blacklisted: Cfx.re blocks this IP from hosting public servers.
- Not blacklisted: the IP is clear to host.
What the Cfx.re blacklist is
Cfx.re keeps a list of IP addresses that may not run public FiveM or RedM servers, usually addresses tied to abuse, ban evasion or hosting ranges that were used for it. A server on a blacklisted IP will not show up in the server list and players get an error when joining. It says nothing about the players on a server, only the machine it runs on.
When to check
- Before renting a VPS or dedicated server. Ask the host for the IP first and check it here.
- When your server vanishes from the list after moving hosts or getting a new IP.
- Before buying a used IP block or a cheap reseller plan.
What you can paste
| Input | What happens |
|---|---|
51.75.12.34 | Checked directly (IPv4 and IPv6). |
play.myserver.com | Every public A and AAAA record is checked. |
cfx.re/join/abc123 or abc123 | Resolved to the server's endpoint, then checked. Servers behind a proxy hide their IP. |
If your IP is blacklisted
Ask your host for a different IP, or contact Cfx.re support through the forum with your server details. Changing ports does not help: the check is by IP.
Private and reserved addresses (LAN, localhost) are not checked. Up to 20 inputs per check, results cached for 10 minutes.
