The Cfx Blacklist Checker tells you whether an IP address is on the Cfx.re platform blacklist. Paste IPs, host names or cfx.re join codes, up to 20 at once, and each address comes back as blacklisted or not. It is for server owners picking a host, moving to a new IP, or wondering why their server is missing from the list.

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 does not show up in the server list, and players get an error when joining. The blacklist is about the machine the server runs on, not about the players on it.

When to check

  • Before renting a VPS or dedicated server. Ask the host for the IP first and check it here. Cheap reseller plans and recycled IPs are the usual suspects.
  • When your server vanishes from the list after moving hosts or getting a new IP.
  • Before buying a used IP block.

Quick start

  1. Paste one or more addresses in IPs, host names or join codes, one per line (spaces and commas work too).
  2. Press Check, or Ctrl + Enter.
  3. Read the result list: every address gets Blacklisted, Not blacklisted or Could not check.

What you can paste

Input What happens
51.75.12.34 Checked directly. IPv4 and IPv6 both work.
play.myserver.com Every public A and AAAA record of the host is checked, so one host can give several rows.
cfx.re/join/abc123 or abc123 Looked up to the server’s address, then checked.

Up to 20 inputs per check.

Reading the results

The header says how many addresses were checked and how many are blacklisted or could not be checked. Each row shows:

  • The IP (click to copy).
  • Under it: the host name it came from, the reverse DNS name when there is one, and a note when something went wrong: a private or reserved address, a host name that did not resolve or has no public IP, a join code that was not found, or a server that hides its address behind a proxy.
  • The state on the right.
State Meaning
Blacklisted This IP may not host a public server.
Not blacklisted The IP is not on the list right now.
Could not check The input could not be turned into a public IP, or the check failed. See the note.

The footer shows when the check ran. Every check gets its own link with ?q=, so you can send the result to your host’s support: /tools/cfx-blacklist-checker?q=51.75.12.34.

Tip

The reverse DNS name often tells you which hosting company owns an IP. Handy when a join code resolves to an address you do not recognise.

If your IP is blacklisted

  • Ask your host for a different IP. Most hosts can swap it, and it is their range that is flagged.
  • If you think the listing is a mistake, contact Cfx.re support through the forum with your server details.
  • Changing ports does not help: the check is by IP.

Limitations

  • Servers behind a proxy hide their address, so a join code check for them comes back as Could not check with a note saying so. Check the real IP directly if you know it.
  • Private and reserved addresses (LAN, 127.0.0.1, 192.168.x.x and so on) are not checked.
  • Results are cached for 10 minutes, so a fresh change on Cfx.re’s side can take a moment to show.
  • A clean result only means the IP is not blacklisted now. It says nothing about the host’s network quality.
