# AllowableIpList

<mark style="color:green;">Whitelist of IPs authorized to connect to the DataServer — any connection from an IP that is not in this list is immediately refused.</mark>

```
0
"127.0.0.1"
end
```

### <mark style="color:yellow;">Notes</mark>

* It must include the IP of every machine running a GameServer or the JoinServer, since they are the ones connecting to the DataServer — if a server is on a different machine, its IP must be here, otherwise the connection will be rejected.
* The comparison requires the exact IP address in quotation marks — it does not accept ranges or wildcards.
