How can i prevent one person to create multiple accounts on same ip

You can prevent two or more people from logging in with the same IP by setting "Allow duplicate IPs" to No in the Server Settings group. There is also a "Allow duplicate PCs" setting. And a blacklist function on the Connections tab. This doesn't stop someone from creating multiple accounts, however, as the server does not associate IP addresses or PCs with specific accounts. If you really wanted to do that, you could disable account creation in the client and only do it via the API where you would do your own checking.
