CFX Resolver for
FiveM Servers

Every public FiveM and RedM server registered with Cfx.re gets a short join code — the b578o4 in cfx.re/join/b578o4. The code is a pointer, not an address: Cfx.re looks it up every time someone connects and answers with wherever the server currently lives. Read how CFX.re join codes work for the full picture.

• Server information — name, project name, owner, game type, locale, tags and current/maximum players.
• Connection data — the connect endpoint the server publishes, and the IPv4/IPv6 address it resolves to.
• Hosting network — ASN, ISP and country of that address, so you can see which provider hosts it.
• Resources — the resource list the server advertises, plus player history and changes once a server is tracked.

Need several at once? Use bulk lookup, compare servers side by side, or browse the FiveM server directory.

CFXR only reads what a server already publishes to Cfx.re's public server list. If the server routes players through a proxy or a DDoS-protection provider, the IP you see belongs to that provider — CFXR does not attempt to find a hidden origin address, and it never connects to the game server itself. Private servers and servers that are offline have no live record, so they cannot be resolved. How CFXR works explains the data sources and limits in detail.

Server details come from Cfx.re's public server-list API, the same source the in-game server browser uses. Endpoints are resolved over public DNS, and network details (ASN, ISP, country) come from public IP-information services. Results are cached for about a minute, so a lookup is close to live without hammering Cfx.re.

Lookups need no account. CFXR never stores your raw IP address — only a keyed hash used for rate limiting and abuse prevention — and lookup logs are deleted after 90 days. The privacy policy lists everything that is kept and for how long.

What is a CFX resolver?

A CFX resolver takes a Cfx.re join code such as b578o4 (or a cfx.re/join link) and asks Cfx.re's public server list which server it points to right now. CFXR then shows the server's published connect endpoint, the IP address that endpoint resolves to, the hosting network behind it, and the server's name, player count and resources.

Can I find a FiveM server's IP address from a CFX code?

Usually, yes. CFXR returns the connect endpoint the server publishes to Cfx.re and resolves it over DNS. If the server sits behind a proxy or a DDoS-protection provider, the address you see is that provider's edge, not the machine the server runs on. CFXR never tries to uncover a hidden origin address.

Which input formats does CFXR accept?

A bare join code (b578o4), a join/ path, a cfx.re/join/ link with or without https://, a fivem://connect/ link and a servers.fivem.net detail URL. Every format is normalised to the same lowercase join code before anything is looked up.

Is CFXR free? Do I need an account?

CFXR is free and has no paid plan. Lookups need no account; an optional free account adds a watchlist, alerts and API keys.

Why does CFXR say a server was not found?

Cfx.re only knows about servers that are currently registered and heartbeating. A server that is offline, private, newly re-keyed or shut down has no live record behind its join code, so there is nothing to resolve.

Resolving a server tells you where it lives, not whether its resources are safe. Read the FiveM server security guide from Titan Software, or scan your resources for backdoors with FXScan.
